RECENT NEWS

new!!! May 16, 2022: The writeup of my talk, entitled A natural mechanism for a SM-like Higgs boson in the 2HDM without decoupling, which was given at the DISCRETE 2020-2021 conference held in Bergen, Norway on December 3, 2021 has now appeared on the arXiv.   [PDF]

February 8, 2022: My presentation to Physics 205 can be found in Section V of this website.

February 7, 2022: Stefano Profumo organized Howie-Fest-70 to celebrate my recent retirement and 70th birthday. The zoom event was recorded, and the recording can be found on the event website. A direct link to the MP4 recording can be found at this link.

January 1, 2022: The 2022 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 8, 2021: Today, I was the (remote) speaker at the NJNU Particle Physics Group weekly seminar series, held at Nanjing Normal University in China. The title of the talk that I gave was Why is the Higgs boson SM-like?. A copy of the slides can be found here:   [PDF].

December 3, 2021: My talk entitled A natural mechanism for a SM-like Higgs boson in the 2HDM without decoupling, given at the DISCRETE 2020-2021 conference held in Bergen, Norway has been posted to Section VII of this website.

The talk discusses a framework for approximate Higgs alignment that is rspsonsible for the SM-like nature of the observed Higgs boson. A softly-broken symmetry of the bosonic sector of the theory will generate violations of the Higgs alignment limit that can be naturally small. This symmetry can be extended to the Yukawa sector by adding vector-like partners to the SM fermions.

December 1, 2021: The 2021 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.

June 10, 2021: Today, my paper in collaboration with João P. Silva, entitled Exceptional regions of the 2HDM parameter space, was published 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.

  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 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.
