Squeezing blood from stone: multivariate methods for higgs search in di-photons at CMS

Speaker: Yuri Gereshtein, Rutgers University

When: March 26, 2012 (Mon), 12:30PM to 01:30PM (add to my calendar)
Location: PRB 595

This event is part of the HET Seminar Series.

Abstract:

I'll describe the results of a search for the light higgs boson decaying into photon pairs 
using the data CMS experiment collected in 2011 LHC run. Although a search for a narrow
resonance may seem straightforward, it turns out that kinematical and instrumental effects
introduce significant complications. To deal with them, CMS collaboration has developed 
several novel multi-variate methods that I will discuss in detail.
