On 27 April 2018, a regular ATLAS weekly working meeting was held at DLNP. O.A. Koval’ (group headed by I.R. Boiko) made a report on the status of the investigations into associative production of the top quark and the Higgs boson. Since this Higgs boson production channel has not been observed yet, the projected research seems to be promising from the point of view of both the investigations of the Standard Model and the search for new physics in the experiments at the LHC.
