RECENT NEWS
May 27, 2019: My talk entitled Approximate alignment without decoupling in the 2HDM naturally, given at the 7th RISE Collaboration Workshop: NonMinimalHiggs in Helsinki, Finland, has been posted to Section VII of this website.
February 18, 2019: My talk entitled Symmetries and Mass Degeneracies in the Scalar Sector, given at HPNP2019 in Osaka, Japan, has been posted to Section VII of this website. This talk incorporates a number of new results and understandings as compared to the two previous presentations on the same subject given in September 2018 in Lisbon and in December 2018 in Warsaw.
January 30, 2019: I have written a set of notes entitled A tale of three diagonalizations, which presents an explicit computation of the diagonalization of a 2x2 matrix. This problem often arises in my work, and I have grown tired of continually rederiving these result when needed. So, these results now appear in one place for future reference. In addition to considering the diagonalization of a normal 2x2 matrix by a unitary similarity transformation, these notes also include an analysis of the singular value decomposition of a complex 2x2 matrix and the AutonneTakagi factorization of a complex symmetric 2x2 matrix. These notes have been posted to Section VI of this website.

January 4, 2019: My paper in collaboration with Odd Magne Ogreid, Per Osland and Margarida Nesbitt Rebelo entitled Symmetries and Mass Degeneracies in the Scalar Sector was published today by the Journal of High Energy Physics (JHEP). A link to this paper can be found in Section II of the academic website.
In this work, we explore some aspects of multiHiggs doublet models that lead to mass degeneracies among some of the physical scalars. Natural scalar mass degeneracies are possible only in the inert two Higgs doublet model (IDM). In the case of three doublets, we introduce and analyze the replicated inert doublet model, which possesses two inert doublets of scalars. We then generalize this model to obtain a scalar potential, which is physically equivalent to a scalar potential first proposed by Ivanov and Silva (IS), with a CP4 symmetry that guarantees the existence of pairwise degenerate scalar states among two of the neutral CPeven, CPodd and charged Higgs scalars. The properties of the CP4symmetric IS model that is not invariant under the conventional CP transformation are examined.
December 31, 2018: Five years after its initial publication, version 4 of The ILC Higgs White paper, which corrects numerous typographical and other minor errors in Chapter 1: Higgs Theory, has been reposted to the arXiv. A link to this paper can be found in Section III of this website.

In this work, we consider the theoretical properties and the phenomenological implications of a generic two Higgs doublet model (2HDM) in the Higgs alignment limit, where the neutral scalar field H_{1} coincides with the properties of the Standard Model (SM) Higgs boson. The properties of the two other heavier neutral Higgs scalars, H_{2} and H_{3}, in the alignment limit are tightly constrained and correlated. Appendices provide a convenient list of 2HDM Feynman rules expressed directly in terms of experimentally observable quantities.

This is the second of a series of papers that explores the physical parameterization, sum rules and unitarity bounds arising from a nonminimal scalar sector of the Standard Model (SM) that consists of N Higgs doublets. In this paper, we focus on the structure and implication of the Yukawa interactions that couple the N scalar doublets to the SM fermions. One consequence of our analysis is the presence of significant constraints on the Higgsfermion coupling in the approximate alignment limit.

August 28, 2018: My paper in collaboration with O.M. Ogreid, P. Osland and M.N. Rebelo, entitled Symmetries and Mass Degeneracies in the Scalar Sector was posted today on the arXiv. A link to this paper can be found in Section II of this website.
In this paper, we explore some aspects of CP conserving models with two and three SU(2) scalar doublets that lead to mass degeneracies among some of the physical scalars. Natural scalar mass degeneracies are possible in the inert two Higgs doublet model (IDM). In the case of three doublets, we introduce and analyze the replicated inert doublet model, which possesses two inert doublets of scalars. We then generalize this model to obtain a scalar potential, first proposed by Ivanov and Silva (IS), with a CP4 symmetry that guarantees the existence of pairwise degenerate scalar states among two of the neutral CPeven, CPodd and charged Higgs scalars. The symmetries of the model permit a term in the IS scalar potential with a complex coefficient that cannot be removed by any redefinition of the scalar fields within the class of Higgs bases (in which case, we say that no real Higgs basis exists and the conventional CP symmetry is absent). Moreover, we demonstrate that it is possible to physically distinguish between the existence or nonexistence of a real Higgs basis despite the fact that no CPviolating observables exist in either case.
August 23, 2018: My paper in collaboration with Miguel P. Bento, Jorge C. Romao and Joao P. Silva, entitled MultiHiggs doublet models: the Higgsfermion couplings and their sum rules was posted today on the arXiv. A link to this paper can be found in Section II of this website.
This is the second of a series of papers that explores the physical parameterization, sum rules and unitarity bounds arising from a nonminimal scalar sector of the Standard Model (SM) that consists of N Higgs doublets. In this paper, we focus on the structure and implication of the Yukawa interactions that couple the N scalar doublets to the SM fermions. We employ the charged Higgs basis introduced in our previous paper. Based on the structure of the Yukawa Lagrangian of the model (and as a consequence of treelevel unitarity), one may deduce numerous sum rules, several of which have not appeared previously in the literature. These sum rules can be used to uncover intimate relations between the structure of the Higgsfermion couplings and the scalar/gauge couplings. In particular, we demonstrate that the approximate alignment limit imposes significant constraints on the Higgsfermion couplings of the model.

August 7, 2018: My paper in collaboration with Bohdan Grzadkowski, Odd Magne Ogreid and Per Osland entitled Heavy Higgs boson decays in the alignment limit of the 2HDM, was posted today on the arXiv. A link to this paper can be found in Section II of this website.
In this work, we consider the theoretical properties and the phenomenological implications of a generic two Higgs doublet model (2HDM) in the Higgs alignment limit, where the neutral scalar field H_{1} coincides with the properties of the Standard Model (SM) Higgs boson. The properties of the two other heavier neutral Higgs scalars, H_{2} and H_{3}, in the alignment limit are tightly constrained and correlated. Observables that could be used to test the alignment scenario at the LHC are defined and discussed. The couplings of the Higgs bosons away from their exact alignment values are determined to leading order, and some consequences are elucidated. Appendices provide a convenient list of 2HDM Feynman rules expressed directly in terms of experimentally observable quantities.

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) TeVscale supersymmetry as a framework for incorporating a weaklycoupled 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 lowenergy 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 twoHiggs 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 basisindependent treatment of the 2HDM. During the past few years, I have focused on the relevance of the socalled decoupling and alignment limits of the 2HDM in which one of scalars closely resembles the SM Higgs boson. The basisindependent 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.

Webpage for Twocomponent 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) 19951996 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 ReEntry, is sponsored by the STARS organization on campus, which provides support and counseling for returning (or reentry) students to campus. You can follow our season exploits on the ReEntry Team Webpage.
