Event Details

On the eve of Run 2, it is useful to review one of the important Higgs searches in CMS Run 1. Dr. Low will present the search for the standard model Higgs boson, produced in association with a W or Z boson, that subsequently decays to a pair of b quarks. Specifically, Dr. Low will focus on the details of the analysis for the decay channel of H -> bb and Z -> neutrinos. A multivariate approach using the boosted decision tree algorithm was applied to improve the analysis sensitivity. We observed a mild excess of events above the expected background with a local significance of 2.1 standard deviations. This excess is compatible with the expectation in the presence of the standard model Higgs boson of mass 125 GeV. The measurements represent the first indication of the H -> bb decays at the LHC, and they are one of the key components in the global fit of the Higgs couplings. If time permits, Dr. Low will also talk about their current involvement in the level 1 track trigger design for the LHC Phase 2 upgrade using associative memory chips for fast pattern recognition and FPGA chips to perform track fitting.
