Contribution

It provides the first comprehensive NLO QCD and EW predictions for off-shell ttH production including non-resonant contributions at the LHC.

Findings

NLO QCD and EW corrections significantly affect cross sections.

Comparison of two correction combination prescriptions.

Results include detailed differential distributions.

Abstract

In these proceedings, next-to-leading-order (NLO) QCD and electroweak (EW) corrections to ${\rm p}{\rm p} \to {\rm e}^+ \nu_{\rm e} \mu^- \bar \nu_\mu {\rm b} \bar{\rm b} {\rm H}$ at the LHC are presented. In these computations the top quarks are considered off their mass shell and all non-resonant contributions are included. The results are presented in the form of fiducial cross sections and differential distributions. Moreover, two prescriptions to combine QCD and EW corrections are examined.
