Seminar

Title: What Can We Learn from Precision Higgs

Speaker: Prof. Maxim Perelstein (Cornell University)

Time: 10:00AM, May 30th (Friday)

Place: Theoretical Physics Division，319

Abstract:

In the coming years, LHC experiments will measure Higgs properties, such as its couplings, with increasing precision. Electron-positron Higgs factories, such as the ILC or TLEP, would be able to achieve even better precision. In this talk, the speaker will discuss some of the physics questions that can be addressed by a precision Higgs coupling measurement program. First, the issue of naturalness of the electroweak scale can be addressed in a robust, model-independent manner. Second, the possibility of a first-order electroweak phase transition can be definitively probed, testing one of the necessary conditions of electroweak baryogenesis scenario.
