Following the discovery of the Higgs boson in 2012, the ATLAS and CMS collaborations have been testing whether the observed boson behaves the same as the boson predicted by the Standard Model. Of particular interest is the interaction between the Higgs and the top quark, the heaviest elementary particle. One way to probe this is to look for events in which a Higgs boson is produced in association with a pair of top quarks and the Higgs boson decays to two bottom quarks. However, this channel suffers from a large background of top quark pairs produced with additional heavy-flavour jets, which is not well understood. The first measurement of ttbb production at 13 TeV by ATLAS will be presented, along with recent measurements of top quark cross-sections.
