Charged Higgs boson production in association with a top quark in MC@NLO

Understand

We discuss the calculation of charged Higgs boson production in association with top quark in the MC@NLO framework for combining NLO matrix elements with a parton shower.

• The process is defined in a model independent manner for wide applicability, and can be used if the charged Higgs boson mass is either greater or less than the mass of the top quark.
• For the latter mass region, care is needed in defining the charged Higgs production mode due to interference with top pair production.
• We give a suitable definition applicable in an NLO (plus parton shower) context, and present example results for the LHC.
