Production and decay of the Higgs boson in association with top quarks

Understand

We report on the calculation of the next-lo-leading order QCD corrections to Higgs boson production and decay in association with top quarks.

• We consider leptonic decays of top quarks leading to the hadronic process $pp\to e^+\nu_e\, \mu^-\bar{\nu}_\mu \, b\bar{b}\,H\, (H\to X)$ at the LHC with $\sqrt{s}=13$ TeV.
• All resonant as well as non-resonant Feynman diagrams, interferences and off-shell effects are included for the top quark and $W$ gauge boson.
• Decays of the Higgs boson, on the other hand, are included in the narrow-width-approximation.
