Theoretical Summary Lecture for Higgs Hunting 2012

In this lecture, I review some of the perspectives on the Higgs boson discussed at the Higgs Hunting 2012 Worshop and discuss the short- and long-term aspects of Higgs physics.Comment: 25 pages, 5 figures, presented at Higgs Hunting 2012, LAL Orsay; figs 3 and 4 updated following version 2 of arXiv:1207.251

CP-odd Phases in Slepton Pair Production

The effects of CP-odd supersymmetric phases on slepton pair production are considered. It is shown that CP-even observables in $e^+ e^-$ and $e^- e^-$ collisions, such as the total selectron cross section, can depend on CP-odd supersymmetric phases through interference between different tree level amplitudes. Left handed selectron pair production in $e^- e^-$ collisions is particularly sensitive to the relative phase between the bino and wino masses. This sensitivity is not limited to any kinematic regime and extends over all of neutralino parameter space. The relative phase between the bino and wino masses is a renormalization group invariant at one-loop, and as such provides a clean probe for operators which violate gaugino universality at the messenger scale.Comment: Latex, 12 pages, 3 figures, to appear in the proceedings of the the Second International Workshop on Electron-Electron Interactions at TeV Energie

Competing Forces in 5-Dimensional Fermion Condensation

We study fermion condensation in the Randall-Sundrum background as a setting for composite Higgs models. We formalize the computation of the Coleman-Weinberg potential and present a simple, general formula. Using this tool, we study the competition of fermion multiplets with different boundary conditions, to find conditions for creating a little hierarchy with the Higgs field expectation value much smaller than the intrinsic Randall-Sundrum mass scale.Comment: 45 pages, 9 figures; v3 has minor typos correction
