Description

We present here the results of the first search for the associated production of the Higgs boson with a $t \bart$ pair, using the events where the Higgs boson decays to two photons in CMS. In order to maximize acceptance and sensitivity to such a small signal, we device two different sets of event selection criteria, optimized for semileptonic and all-hadronic $t \bar t$ decays.
