Evidence for ttH Production with the ATLAS experiment

Abstract:

The top quark Yukawa coupling can be probed directly by exploiting the unique experimental signature when the Higgs boson is produced in association with a pair of top quarks. 
This so-called ttH production could also be sensitive to new physics for example through higher dimensional operators. The ATLAS experiment has recently obtained 4.2 sigma evidence 
for ttH production. I will discuss these results and highlight some of the important experimental challenges.
