October 25, 2024: My talk entitled Flavor-nondiagonal neutral Higgs Yukawa couplings revisited, given at the Extended Scalar Sectors From All Angles workshop at CERN, has been posted to Section VII of this website.
September 4, 2024: My paper entitled Explicit form for the most general Lorentz transformation revisited was published in the journal Symmetry. A link to this paper can be found in Section II of this website.
Explicit formuale for the 4x4 Lorentz transformation matrices corresponding to a pure boost and a pure three-dimensional rotation are very well-known. Significantly less well-known is the explicit formula for a general Lorentz transformation with arbitrary boost and rotation parameters. We revisit this more general formula by presenting two different derivations, which are shown to yield the same result. The first derivation evaluates the exponential of a 4x4 matrix by making use of the Lagrange interpolating polynomial. The second derivation exploits the assertion that for two-component spinors η and χ, the spinor product ησμχ† is a Lorentz four-vector. As a result, the formula for a general Lorentz transformation reduces to the computation of the trace of a product of 2x2 matrices.

February 19, 2024: I could not find in the literature closed-form expressions for the two-loop Barr-Zee diagram integrals. So, I went ahead and derived these results, which can be expressed in terms of dilogarithms or the Clausen function (depending on the value of a parameter). A short note presenting the derivation, entitled Evaluating integrals arising from Barr-Zee diagrams, has been posted to Section VI of this website.
February 13, 2024: Today, my paper in collaboration with Miguel Bento and Joao Silva, entitled Classes of complete dark photon models constrained by Z-physics, was published in Physics Letters B. A link to this paper can be found in Section II of this website.
Dark Matter models that employ a vector portal to a dark sector are usually treated as an effective theory that incorporates kinetic mixing of the photon with a new U(1) gauge boson, with the Z boson integrated out. However, a more complete theory must employ the full SU(2)L×U(1)Y×U(1)Y' gauge group, in which kinetic mixing of the Z boson with the new U(1) gauge boson is taken into account. The importance of the more complete analysis is demonstrated by an example where the parameter space of the effective theory that yields the observed dark matter relic density is in conflict with a suitably defined electroweak ρ parameter that is deduced from a global fit to Z physics data.
January 9, 2024: The 2023 update of the Supersymmetry (Theory) review that appears in the Review of Particle Physics by the Particle Data Group (PDG) was published online on December 1, 2023 (see news item below). To make it widely accessuble, this review was posted on the arXiv today. A link to the arXiv version of this review can be found in Section II of this website.
December 29, 2023: The 2024 Particle Physics conference schedule has been posted to Section VIII of this website. Although not intended to be comprehensive, it covers many conferences that overlap with my research interests.

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).
After more then ten years after the discovery of the Higgs boson in 2012 at the Large Hadron Collider (LHC), many properties of this spin-zero particle have been measured. These results 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; Phys. Rev. D Server
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 v6 of our review with the (-1, +1, +1, +1) metric
convention, which should be identical in content in every other
respect:
DHMspinors_v6.pdf.
Both the (+1,-1,-1,-1) and the (-1, +1, +1, +1) metric versions were made
from the same source files available from the arXiv.
The choice of metric signature is implemented by simply changing
a single character in the main LaTeX source file, namely the
argument
of line 20, with \def\signofmetric{0} corresponding
to the (+1,-1,-1,-1) metric and \def\signofmetric{1} to the
(-1, +1, +1, +1) metric. Note that the pdf file is produced with pdflatex.
The list of known corrections to the Physics Reports version as of May 2022
is here:
DHM_corr_PhysicsReports.pdf.
These corrections have all been implemented (along with some
additional enhancements) and can be found in
version
6 of arXiv:0812.1594 (313 pages, May 2022).
Any subsequent corrections to version
6 of arXiv:0812.1594 will be posted on
https://www.niu.edu/spmartin/spinors/.

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.
