The Experimental Investigation of Supersymmetry Breaking

If Nature is supersymmetric at the weak interaction scale, what can we hope to learn from experiments on supersymmetric particles? The most mysterious aspect of phenomenological supersymmetry is the mechanism of spontaneous supersymmetry breaking. This mechanism ties the observable pattern of supersymmetric particle masses to aspects of the underlying unified theory at very small distance scales. In this article, I will discuss a systematic experimental program to determine the mechanism of supersymmetry breaking. Both $pp$ and $e^+e^-$ colliders of the next generation play an essential role.

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

Estimation of LHC and ILC Capabilities for Precision Higgs Boson Coupling Measurements

This paper discusses some aspects of the estimates of Higgs boson coupling sensitivities for LHC and ILC presented at the Snowmass 2013 meeting. I estimate the measurement accuracies underlying the CMS presentation to Snowmass. I present new fits for the ILC capabilities. I present some joints fits to prospective LHC and ILC data that demonstrates the synergy of the High-Luminosity LHC and ILC programs. Contributed to the proceedings of the Snowmass 2013 Community Summer Study.Comment: 23 pages, 4 figures; v3 - minor clarifications adde
