The Higgs Boson Explained from PHD Comics on Vimeo.

March 13, 2012: American Physical Society Viewpoint by Howard E. Haber: Homing in on the Higgs Boson.

I. Research

The basic themes underlying my research program are: (i) the elucidation of the dynamics responsible for electroweak symmetry breaking; (ii) the viability of low-energy supersymmetry as a model of electroweak interactions; (iii) the unification of fundamental particles and their interactions; and (iv) the search for physics beyond the Standard Model at present and future colliders.

The phenomenology of the Higgs boson sector is intimately tied to the origin of electroweak symmetry breaking. In particular, the two-Higgs doublet model (2HDM) is a key component of the simplest supersymmetric extension of the Standard Model. The theoretical structure and phenomenological profile of the 2HDM has attracted much attention in recent years. My recent works have advocated the importance of a basis-independent treatment of the 2HDM. If future collider experiments provide evidence for a 2HDM structure, it will be critical to establish model-independent techniques for probing the fundamental Higgs boson interactions.

If nature is indeed supersymmetric, it will also be essential to develop techniques for measuring new particle interaction strengths at high energy colliders. With sufficient precision, it will be possible to provide convincing evidence for or against a supersymmetric interpretation of new fundamental physics phenomena.

IX. 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.
