Performance of top kinematic fit algorithm on tt¯H events

Production of top quark and anti-top quark pair associated with a Higgs boson (tt¯H) production is one of the experimental probes for measuring the Higgs boson to top quark coupling. Since the full kinematic information is required to study such production, a precise technique to fully reconstruct tt¯H events is needed. This work reports our very first attempt to reconstruct tt¯H events using a kinematic fit algorithm that has been established and has commonly used to reconstruct tt¯ events at the Tevatron and Large Hadron Collider (LHC). The results imply that HitFit was able to perform well on tt¯H events.
