Particle Detector Development and Performance

First results of a search for the Standard Model Higgs boson produced in association with a top quark-antiquark pair (ttH) in proton-proton collisions at a center of mass energy of 13 TeV is presented. The decays of Higgs boson into two photons, bottom quark-antiquark pair and multileptons via WW, ZZ and tautau pairs are analysed separately and then combined. The results are presented in terms of the best-fit signal strength relative to the Standard Model prediction and the observed and expected upper limits at the 95% confidence level are extracted.
