February 22, 2021: My pedagogical review entitled A tale of three
diagonalizations was published today in the International
Journal of Modern Physics A. A link to this paper can be found in Section II of
this website.
In addition to the diagonalization of a normal matrix by a unitary similarity transformation, there are two other types of diagonalization procedures that sometimes arise in quantum theory applications--the singular value decomposition and the Autonne-Takagi factorization. In these notes, each of these diagonalization procedures for the most general 2×2 matrices for which the corresponding diagonalization is possible is explicitly derived and analytical results in each of the three cases are presented.
February 16, 2021: My paper in collaboration with João P. Silva, entitled Exceptional regions of the 2HDM parameter space, was posted today on the arXiv. A link to this paper can be found in Section II of this website.
This paper provides a comprehensive treatment of the exceptional region of the 2HDM parameter space (dubbed the ERPS4) whose scalar potential parameters (using the standard parameterization) satisfy λ1= λ2 and λ6= -λ7. Such a scalar potential exhibits a generalized CP symmetry, called GCP2, that is softly-broken if m11≠ m22 and/or m12 ≠ 0. Many of the special features of the ERPS4 are highlighted, as well as the properties of even more specialized cases within the ERPS4 framework in which additional constraints on the scalar potential parameters are imposed. Implications for CP violation, the Higgs alignment limit and custodial symmetry are examined.
January 20, 2021: My review entitled Useful relations among the generators in the defining and adjoint representations of SU(N) was published today in SciPost Physics Lecture Notes. A link to this paper can be found in Section II of this website.
There are numerous relations among the generators in the defining and adjoint representations of SU(N). These include Casimir operators, formulae for traces of products of generators, etc. Many of these relations are well known and others are more obscure. There are multiple sources for the various identities that are reviewed in this note, but there is no single reference that I am aware of that contains all of them. I have collected many of the relevant identities and assembled them in this short review.
January 19, 2021: My presentation to Physics 205 can be found in Section V of this website.
January 1, 2021: The 2021 Particle Physics conference schedule has been posted to Section VIII of the academic website. Although not intended to be comprehensive, it covers many conferences that overlap with my research interests.
December 31, 2020: The report of the "Precision SUSY Higgs Mass Calculation Initiative", co-authored with Pietro Slavich et al., has appeared on the arXiv today. A link to this paper can be found in Section II of this website.
Predictions for the Higgs masses are a distinctive feature of supersymmetric extensions of the Standard Model, where they play a crucial role in constraining the parameter space. The "Precision SUSY Higgs Mass Calculation Initiative" (KUTS) was launched in 2014 to provide a forum for discussions between the different groups involved in these efforts. This report aims to present a comprehensive overview of the current status of Higgs-mass calculations in supersymmetric models, to document the many advances that were achieved in recent years and were discussed during the KUTS meetings, and to outline the prospects for future improvements in these calculations.
November 30, 2020: My paper in collaboration with Patrick Draper and Andreas Ekstedt, entitled A natural mechanism for approximate Higgs alignment in the 2HDM, was posted today on the arXiv. A link to this paper can be found in Section II of this website.
In this paper, we provide a mechanism for obtaining an approximate Higgs alignment suggested by the LHC Higgs data as a consequence of a softly broken global symmetry of the two-Higgs doublet model (2HDM) Lagrangian. However, this can only be accomplished if the Yukawa sector of the theory is extended. Thus, we propose an extended 2HDM with vector-like top quark partners, where explicit mass terms in the top sector provide the source of the soft symmetry breaking of a generalized CP symmetry. In this way, we can realize approximate Higgs alignment without a significant fine-tuning of the model parameters. The implications of the current LHC bounds on vector-like top quark partners for the success of our proposed scenario are explored.
September 10, 2020: A pedagogical note entitled A tale of three diagonalizations was posted today on the arXiv. A link to this paper can be found in Section II of this website.
August 14, 2020: The 2020 edition of the Review of Particle Physics, published today in Progress of Theoretical and Experimental Physics (PTEP), provides a comprehensive review of the field of particle physics and of related areas in cosmology. Topics include Higgs bosons, supersymmetry, big bang nucleosynthesis, probability, statistics, and accelerators and detectors. The latest update of my Supersymmetry Theory review in collaboration with Ben Allanach, which appears in the Review of Particle Physics, can be found in Section III of the academic website.
August 1, 2020: As of today, I have been recalled to active service for three years (without salary). My new title at the University is Research Professor of Physics. This will permit me to continue my research activities in theoretical particle physics. I look forward to continuing my collaborations both here and abroad (at least via zoom until the day arrives that will allow us to travel once again).
July 1, 2020: I have officially retired from the University of California, Santa Cruz, and henceforth my designation will be Distinguished Professor of Physics Emeritus. Although my teaching duties are now complete, I am still supervising two Ph.D. students, and I will consider the possibility of teaching occasionally in the future if the opportunity presents itself.
May 30, 2020: I have written some notes that provide an explicit computation of the finite part of the Passarino-Veltman function B0(p2;m12,m22), which appears in the evaluation of one-loop self-energy diagrams. This note has been posted to Section VI of this website.
April 20, 2020: I have posted two sets of notes to Section VI of this website. The first note consists of a careful derivation of the expression for the Feynman propagator of scalar field theory, ΔF(x) in coordinate space (in four spacetime dimensions). Two different treatments are given and various subtleties of the calculations are emphasized. ΔF(x) is an example of a generalized function (or distribution). In the second note, I provide a practical introduction to generalized functions that is particularly useful in mathematical physics applications, focusing on identifying the most common generalized functions employed in physics and the methods for manipulating them.
March 29, 2020: I have prepared a note entitled, Evaluating the one-loop function arising in h→γγ. This note has been posted to Section VI of this website.
March 20, 2020: My paper in collaboration with Rafael Boto, Tiago V. Fernandes, Jorge C. Romao and Joao P. Silva, entitled Basis-independent treatment of the complex 2HDM, was published today in Physical Review D. A link to this paper can be found in Section II of this website.

I. Research
The basic themes underlying my research program involve the study of: (i) the dynamics responsible for electroweak symmetry breaking; (ii) the theory and phenomenology of Higgs bosons; (iii) TeV-scale supersymmetry as a framework for incorporating a weakly-coupled Higgs sector; (iv) the phenomenology of signals for new physics beyond the Standard Model at the Large Hadron Collider (LHC) and future colliders; and (v) connections of low-energy phenomena with fundamental scales that lie beyond the TeV scale (e.g. lepton number violation and implications for neutrino masses).
The properties of the Higgs boson, which were discovered in 2012 at the Large Hadron Collider (LHC). have profound implications for the dynamics of electroweak symmetry breaking and the possible structure of new physics that may lie beyond the Standard Model (SM) of particle physics. For example, most approaches to physics beyond the SM include extended Higgs sectors. Present Higgs data suggest that the properties of one of the scalars of the Higgs sector (identified with the observed Higgs boson) must have properties that closely approximate that of the SM Higgs boson. This constraint in turn imposes important constraints on any SM extension. The two-Higgs doublet model (2HDM) is a convenient theoretical laboratory for the study of extended Higgs sectors. Indeed, the two doublet extended Higgs sector is a key component of the simplest supersymmetric extension of the SM.
The theoretical structure and phenomenological profile of the 2HDM has attracted much attention in recent years. Staring with a seminal paper in collaboration with Sacha Davidson published in 2005, my work has advocated the importance of a basis-independent treatment of the 2HDM. During the past few years, I have focused on the relevance of the so-called decoupling and alignment limits of the 2HDM in which one of scalars closely resembles the SM Higgs boson. The basis-independent technology provides a very powerful and simple framework for studying and interpreting these limits.
If new physics beyond the SM emerges at the LHC, it will be essential
to develop techniques for measuring new particle interaction strengths at
high energy colliders. By detecting relations among various independent
couplings, one can ascertain underlying symmetries and distinguish
among different theoretical interpretations of the new physics. For example,
with sufficient precision, it will be possible to provide convincing
evidence for or against a supersymmetric interpretation of new
fundamental physics phenomena. A precision Higgs program at the LHC
and at a future collider (such as the proposed International Linear Collider)
can also provide important clues as to what may lie beyond the Standard Model.

Abstract and Postscript and PDF from arXiv.org; Journal Server - Phys.Rept.
Webpage for Two-component spinor techniques and Feynman rules for quantum field theory and supersymmetry, maintained by Stephen P. Martin. Both the arXiv version and the Physics Reports version use the spacetime metric signature (+1,-1,-1,-1), as is found for example in the field theory textbooks by Ramond, and by Peskin and Schroeder . However, many people including one of the authors (S.P. Martin) prefer the metric signature (-1, +1, +1, +1), as is found for example in the textbooks by Weinberg, by Wess and Bagger, by Srednicki, and in Martin's Supersymmetry Primer. Here is a PDF file of v5 of our review with the (-1, +1, +1, +1) metric convention, which should be identical in content in every other respect: DHMspinors_v5.pdf.
The list of known corrections to the Physics Reports version (September 2010) is here: DHM_corr_PhysicsReports.pdf.
The list of known corrections to the arXiv v5 (311 pages, August 2010) is here: DHM_corr_v5.pdf.
Both the (+1,-1,-1,-1) and the (-1, +1, +1, +1) metric versions were made
from the single LaTeX file
DHMspinors_v5.tex.
[If you are curious and want to LaTeX this for some reason, you may need
the style files found
here; other packages used should be in most standard LaTeX
distributions.
The choice of metric signature is implemented by simply changing
a single character in the LaTeX file, namely the
argument
of line 16, with \def\signofmetric{0} corresponding
to the (+1,-1,-1,-1) metric and \def\signofmetric{1} to the
(-1, +1, +1, +1) metric.]

IX. University Service
Faculty Perceptions of a UCSC Research Environment in Need of Restoration and Improvement, a report by Howard E. Haber and David M. Harrington, sponsored by the UCSC Committee on Research and contributed in May, 1998 to the Advisory Report of the Millennium Committee. [HTML]
University Committee on Research Policy (UCORP) 1995--1996 Public web page.
Should UC renew its contract with the Department of Energy (DOE) to manage the Lawrence Livermore National Laboratory and Los Alamos National Laboratory? The following web page documents the 1996 UC systemwide campus debate on this question. A town meeting was held on the UCSC campus on March 7, 1996 to discuss these issues.
X. Extracurricular Activities
Some of the physics students and I play softball in the UCSC intramural coed softball league. The fall season runs from early October to early December, and the spring season runs from early April to early June.
Our team, called Re-Entry, is sponsored by the STARS organization on campus, which provides support and counseling for returning (or re-entry) students to campus. You can follow our season exploits on the Re-Entry Team Webpage.
