Optimization of a search for a resonance decaying into a Z boson and a Higgs boson

The aim of this CERN Summer School Project is to optimize a search for a heavy vector resonance which subsequently decays into a Z boson and a Higgs boson: pp → A → Zh. The search channel considered in this project is Zh → b¯bW W* → b¯blvqq, where the Z boson decays into two bottom quarks and the Hi...

description The aim of this CERN Summer School Project is to optimize a search for a heavy vector resonance which subsequently decays into a Z boson and a Higgs boson: pp → A → Zh. The search channel considered in this project is Zh → b¯bW W* → b¯blvqq, where the Z boson decays into two bottom quarks and the Higgs boson decays into two W bosons. This signature has an irreducible background from the tt¯ decay. In this project we exploit the power of multivariate analysis to construct a multivariate discriminant in order to reject the tt¯ background while keeping the signal efficiency high.
