RECENT NEWS
January 10, 2017: The official writeup of my talk given at the Sixth International Workshop on the Prospects for Charged Higgs Discovery at Colliders (CHARGED 2016) in Uppsala, Sweden on October 6, 2016 has now appeared on the arXiv. [Postscript  PDF]
January 2, 2017: The 2017 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 16, 2016: My talk entitled High scale flavor alignment in the 2HDM and its phenomenology, given at the Helsinki Higgs Forum in Helsinki, Finland, has been posted to Section VII of the academic website.
November 18, 2016: After a season of rainouts and forfeits, Team ReEntry
finally got to play a meaningful game, as the two undefeated teams
of the UCSC Coed Softball league met in the Championship
game. ReEntry dominated "Where my pitches at" with a convincing
152 victory in a game that was called early due to the impending
darkness. The three year drought is now over, as ReEntry claimed
its eleventh championship since 1996. For
further details, check out the
UCSC Coed
Softball ReEntry Team Webpage.
November 17, 2016: Q&A: What more can we learn about the Higgs? Four physicists (myself included) discuss Higgs boson research since the discovery with Angela Anderson of Symmetry Magazine (a joint Fermilab/SLAC publication).
November 11, 2016: My talk entitled SUSY and the alignment limit, given at Higgs Couplings 2016 at SLAC has been posted to Section VII of this website.
November 3, 2016: My paper in collaboration with Michael Dine, Patrick Draper and Laurel Stephenson Haskins entitled Perturbation theory in supersymmetric QED: Infrared divergences and gauge invariance was published today in Physical Review D. In this paper, we examine some aspects of perturbation theory in N=1 SUSY QED. In general Rgauges, IR divergences and nonlocal behavior arise in 1PI diagrams, associated with a 1/k^{4} term in the propagator for the vector superfield. We demonstrate that in the computation of the electron pole mass, the cancellation of the IR divergences takes place in a nontrivial way, amounting to a reorganization of the perturbative series from powers of e^{2} to powers of e. A link to this paper can be found in Section II of this website.
October 10, 2016: The American Physical Society has announced that Gordon Kane, Howard
Haber, John Gunion and Sally Dawson have been awarded the 2017
J.J. Sakurai Prize for Theoretical Particle Physics. Further

August 3, 2016: My paper in collaboration with Philip Bechtle, Sven Heinemeyer, Tim Stefaniak, Oscar Stål, Georg Weiglein, and Lisa Zeune entitled The Light and Heavy Higgs Interpretation of the MSSM was posted today on the arXiv. A link to this paper can be found in Section II of this website.
In this paper, we performed a parameter scan of the eightparameter pMSSM taking into account the experimental Higgs boson results from Run I of the LHC as well as additional lowenergy observables. We investigated various MSSM interpretations of the Higgs signal at 125 GeV, in which the observed Higgs boson is identified with either the lightest or heaviest CPeven Higgs scalar of the MSSM. We identified regions close to the alignment limit without decoupling, in which the other Higgs scalars of the MSSM can also be light, offering good prospects for upcoming LHC searches and searches at future colliders.
July 26, 2016: My paper in collaboration with Michael Dine, Patrick Draper and Laurel Stephenson Haskins entitled Perturbation Theory in Supersymmetric QED: Infrared Divergences and Gauge Invariance was posted today on the arXiv. A link to this paper can be found in Section II of this website.
In this paper, we investigated some aspects of the perturbation theory in N=1 supersymmetric gauge theories with massive charged matter. In general gauges, infrared divergences and nonlocal behavior arise in 1PI diagrams, associated with a 1/k^{4} term in the propagator for the vector superfield. We have examined this structure in supersymmetric QED. The IR divergences are gaugedependent and must cancel in physical quantities like the electron pole mass. However, this cancellation takes place in a nontrivial way, amounting to a reorganization of the perturbative series from powers of e^{2} to powers of e (where e is the γe^{+}e^{} coupling constant).
July 6, 2016: My talk entitled Extended Higgs sectors and the alignment limit, given at the 24rd International Conference on Supersymmetry and Unification of Fundamental Interactions (SUSY 2016) has been posted to Section VII of this website.
July 1, 2016: Today I gave the last of three lectures entitled SM and SUSY Higgs at preSUSY 2016 in Melbourne, Australia. Links to the PDF slides of the three lectures can be found in Section VII 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) 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.
