RECENT NEWS

new!!! 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 eight-parameter pMSSM taking into account the experimental Higgs boson results from Run I of the LHC as well as additional low-energy 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 CP-even 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/k4 term in the propagator for the vector superfield. We have examined this structure in supersymmetric QED. The IR divergences are gauge-dependent 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 e2 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 pre-SUSY 2016 in Melbourne, Australia. Links to the PDF slides of the three lectures can be found in Section VII of this website.

June 21, 2016: My paper in collaboration with Patrick Draper and Josh Ruderman entitled Partially Natural Two Higgs Doublet Models was published today in the Journal of High Energy Physics (JHEP). This paper examines the number of independent fine-tunings required in the two Higgs doublet model (2HDM) and demonstrates under what circumstances the number of fine-tunings of the 2HDM can be reduced to the one fine tuning that sets the electroweak scale in the Standard Model. A link to this paper can be found in Section II of this website.

June 15, 2016: Today I gave the last of four lectures entitled Supersymmetric Theory and Models at the 2016 Theoretical Advanced Study Institute (TASI 2016) in Boulder, CO. Links to the PDF slides of the four lectures can be found in Section VII of this website.

June 6, 2016: The erratum to my paper in collaboration with Oscal Stål entitled New LHC Benchmarks for the CP-conserving Two-Higgs-Doublet Model was published today in European Physical Journal C. A link to this erratum can be found in Section II of this website.

June 3, 2016: The Re-Entry softball team met up with the Might Shmucks in the Championship game of the UCSC Friday late afternoon coed softball league. Re-Entry came back from an eight run deficit to take a one run lead in the penultimate inning. After giving up two runs in the top of the last inning, Re-Entry attempted one last comeback. But, with the tying and winning runs on base, Re-Entry was unable to produce the game winning hit. The result was a one run loss in the Championship game for the third time since the fall of 2012. For further details, check out the UCSC Coed Softball Re-Entry Team Webpage.

May 17, 2016: A corrected version of my paper in collaboration with Oscal Stål entitled New LHC Benchmarks for the CP-conserving Two-Higgs-Doublet Model was uploaded today to the arXiv. A link to this paper can be found in Section II of this website. An official erratum will be published soon in the European Physics Journal C.

May 12, 2016: My paper in collaboration with Patrick Draper and Josh Ruderman entitled Partially Natural Two Higgs Doublet Models was posted today on the arXiv. A link to this paper can be found in Section II of this website.

In this paper, we consider the implications of a discovery of new light fundamental scalars other than the Standard Model Higgs boson, under the assumption that the electroweak symmetry breaking scale is fine-tuned (perhaps as a result of selection effects). In this latter case, the common wisdom is that all additional elementary scalars must be heavy. We discuss counterexamples where the Higgs boson is light because of fine-tuning, and a second scalar doublet is light because a discrete symmetry relates its mass to the mass of the Standard Model Higgs boson. Our examples require new vectorlike fermions at the electroweak scale, and the models possess a rich electroweak vacuum structure.

April 18, 2016: My talk entitled Revisiting the 2012 Higgs Wishlist, given at the KITP Workshop on Experimental Challenges for the LHC Run II has been posted to Section VII of this website.

February 29, 2016: My paper in collaboration with Jérémy Bernon, John F. Gunion, Yun Jiang and Sabine Kraml entitled Scrutinizing the Alignment Limit in Two-Higgs-Doublet Models. II.: mH=125 GeV was published today in Physical Review D. In this paper, we examine the theoretical structure and the phenomenological implications of the alignment regime of the 2HDM (with and without decoupling) where the couplings of the heavier of the two CP-even Higgs scalars are nearly indistinguishable from those of the Standard Model (SM) Higgs boson. Implications for Run 2 at the LHC, including expectations for observing the non-SM-like scalar states, are considered. A link to this paper can be found in Section II of this website.

February 19, 2016: The Particle Data Group (PDG) announces that updated PDG review articles for the 2016 edition of the Review of Particle Physics are now available at http://pdg.lbl.gov/. In particular, check out my updated review of Supersymmetry, Part I (Theory).

February 17, 2016: My paper, in collaboration with Marcela Carena, Ian Low, Nausheen Shah and Carlos Wagner, entitled Alignment limit of the NMSSM Higgs sector was published today in Physical Review D. In this paper, we identify the Higgs alignment region of the NMSSM parameter space where the observed Higgs boson is predicted to have SM-like properties. The alignment limit in the NMSSM leads to a well defined spectrum in the Higgs and Higgsino sectors, and yields a rich and interesting Higgs boson phenomenology that can be tested at the LHC. A link to this paper can be found in Section II of this website.

January 11, 2016: My presentation to Physics 205 can be found in Section V of this website.

January 3, 2016: The 2016 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 31, 2015: My three year term as Secretary-Treasurer of the Division of Particles and Fields of the American Physical Society has now come to an end. Best of luck to my successor, Kate Scholberg!

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 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 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. My recent work has advocated the importance of a basis-independent treatment of the 2HDM. Recently, 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.

  3. 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.
