Description

The $t\bar{t}H$ production process probes the top-Higgs Yukawa coupling directly which is especially sensitive to the underlying physics. The measurement of the $pp \to t\bar{t}H$ cross section is among the highest priorities of the current LHC physics program and improvement of the theoretical accuracy is of the central importance. In this talk the latest results for soft gluon resummation at fixed invariant mass for $pp \to t\bar{t}H$ will be presented. The resummation is extended to next-to-next-to-leading logarithmic accuracy. The invariant mass resummation results will be presented in the form of the inclusive cross section and the invariant mass distribution, including scale uncertainty.
