RECENT NEWS

new!!! December 1, 2023: The 2023 update of the review articles appearing the Review of Particle Physics by the Particle Data Group (PDG) is now published on the PDG web site. Included among these review articles is the newly revised Supersymmetry, Part I (Theory), which is co-authored by myself and Ben Allanach.

November 10, 2023: Today, my paper in collaboration with Miguel Bento and Joao Silva, entitled Classes of complete dark photon models constrained by Z-physics, was posted on the arXiv. 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.

October 30, 2023: Today, my paper entitled Higgs Boson Physics: The View Ahead was published in a special issue of Letters in High Energy Physics (LHEP) on Higgs physics, and beyond, after 10 years since the discovery. A link to this paper can be found in Section II of this website.

October 13, 2023: Today, my paper in collaboration with Miguel Bento and Joao Silva, entitled Tree-level Unitarity in SU(2)L×U(1)Y×U(1)Y'​ Models, was published in JHEP. A link to this paper can be found in Section II of this website.

In models with a U(1) gauge extension beyond the Standard Model, one can derive sum rules for the couplings of the theory that are a consequence of tree-level unitarity. In this paper, we provide a comprehensive list of coupling sum rules for a general SU(2)L×U(1)Y×U(1)Y'​ gauge theory coupled to an arbitrary set of fermion and scalar multiplets. For the case of a minimal extension of the Standard Model with a U(1)Y' gauge boson, the definitions of the weak mixing angle and the electroweak ρ parameter are clarified, and a generalized ρ parameter (denoted by ρ′) is defined. The latter naturally follows from the unitarity sum rules developed in this paper.

September 28, 2023: Today, my paper in collaboration with Joseph (Zippy) Connel and Pedro Ferreira, entitled Accommodating Hints of New Heavy Scalars in the Framework of the Flavor-Aligned Two-Higgs-Doublet Model, was published in Physical Review D. A link to this paper can be found in Section II of this website.

Searches for new neutral Higgs bosons of an extended Higgs sector at the LHC can be interpreted in the framework of the two-Higgs doublet model. By employing generic flavor-aligned Higgs–fermion Yukawa couplings, we propose an analysis that uses experimental data to determine whether flavor alignment is a consequence of a symmetry that is either exact or at most softly broken. We illustrate our proposal in two different scenarios based on a few 3 sigma (local) excesses observed by the ATLAS and CMS Collaborations in their searches for heavy scalars at Run 2 of the LHC.

September 13, 2023: My talk entitled Scalar revelations at future e+e- colliders, given at Scalars 2023 at the University of Warsaw in Warsaw, Poland, has been posted to Section VII of this website.

January 2, 2023: The 2023 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.

December 18, 2022: Today I posted a short note to Section VI of this website entitled Exponentiating the Lie algebra of the Lorentz group. In one method, the 4x4 Lorentz transformation matrix (for arbitrary boost and rotation parameters) is obtained by an explict computation of the exponential of the corresponding element of the SO(1,3) Lie algebra. In a second method, the four-vector nature of the spinor product with a free spacetime index is used to to obtain the matrix Λ, which only requires the exponentiation of 2x2 matrices. The two methods are shown to yield the same expression for Λ.

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.

    7. 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.
