Title: A new approach to Higgs Effective Field Theory
Speaker: Kyle Cranmer (NYU)
Abstract:
Detailed characterization of the Higgs particle in the language of Effective Field Theory is one of the science drivers for the LHC and potential future colliders. Deviations from the Standard Model Higgs expectation are typically encoded in subtle deviations and correlations in event kinematics. This motivates the use of multivariate techniques that take advantage of a high-dimensional representation of each event. Surprisingly, our field doesn’t have a good technique for measuring parameters of a theory when one needs to incorporate a complicated detector response and wants to take advantage of the information of a high-dimensional observation. I will outline a novel “likelihood-free” inference technique that addresses this problem and its application to Higgs Effective Field Theory.
