The most important goal of the Large Hadron Collider (LHC) is to elucidate the mechanism of electroweak symmetry breaking. The Standard Model(SM) Higgs Boson is thought to be a prime candidate for this. Recent observations of a new boson with mass of 125GeV are consistent with a SM Higgs, however the properties of this new
particle must now be understood in order to say anything conclusive about its relationship to a SM Higgs. The observation of this new particle in association with top quarks would allow the couplings of this particle to top and bottom quarks to be measured. t¯tHiggs, Higgs to b¯b is an excellent branch to explore due to the dominant branching ratio of Higgs to b¯b and the kinematic handle the t¯t offers on the event.
However, it presents some difficult challenges due to a low signal to background ratio and uncertainties of SM backgrounds. This talk describes a search for the SM Higgs boson in association with top quarks, using Monte Carlo (MC) simulations. MC to Data comparisons are
made with pp collisions collected by the CMS detector.
