Description
The current status on the search for the production of the Higgs boson with a top quark
pair (ttH) using proton-proton collision data at a center-of-mass energy of 13 TeV is
reported. The ttH production allows to constrain the top Yukawa coupling, which is a key
parameter of the Standard Model and its direct measurement through the ttH production
mode is one of the most challenging physics program at LHC.
The ATLAS collaboration recently claimed for the evidence of this process after the
explorative analysis of the full 2015 and 2016 dataset. The details of the analysis that
led to the evidence, together with the state of the art of the CMS collaboration ttH
search analysis, will be reviewed.
