June 3, 2014: My paper in collaboration with Pedro Ferreira, Rui Santos and John Gunion, entitled Probing wrongsign Yukawa couplings at the LHC and a future linear collider was published today in Physical Review D. This paper discusses the possibility that all couplings of the recently discovered Higgs boson are close to their Standard Model values in magnitude, but the overall sign of Higgs coupling to downtype fermions is reversed as compared to its Standard Model value. Prospects for detecting this wrongsign Yukawa coupling at the LHC and ILC are investigated. A link to this paper can be found in Section II of the academic website.

This paper discusses the possibility that all couplings of the recently discovered Higgs boson are close to their Standard Model values in magnitude, but the overall sign of Higgs coupling to downtype fermions is reversed as compared to its Standard Model value. The possibility of achieving this in a TypeII two Higgs doublet model is demonstrated, and the prospects for detecting this wrongsign Yukawa coupling at the LHC and ILC are investigated.

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 newly discovered Higgs boson 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. My recent work has advocated the importance of a basisindependent treatment of the 2HDM. Recently, 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.
