Charged Higgs production with a top in MC@NLO

Understand

The production in association with a top quark is the most promising search channel for charged Higgs bosons at the LHC.

• We review its theoretical description including next-to-leading order corrections and the combination with a parton shower.
• The latter allows us to for the first time answer questions about the kinematics of all jets in the process.
• We then describe the consistent subtraction of intermediate states and present new results about the bottom mass uncertainty impacting the parton densisities.
