Description
Analysis considers the Z boson production in association with two
b quark jets when the Z boson decays into an electron or muon pair.
The dominant background in these final states come from the ttbar
production when W bosons decay to charged and neutral leptons, the
latter resulting in the missing transverse energy (MET) in the event.
Results will be reported on data-driven methods to optimize the
MET selection and derive the corresponding factors that correct for
imperfect simulations of the ttbar process.
