NLO QCD off-shell effects for top pair production with a jet in the dilepton channel

Understand

A short summary of a NLO QCD calculation for the top-quark pair production with a jet in the dilepton decay channel is presented.

• The calculation takes into account all double, single, non-resonant and interference contributions.
• Thus, NLO QCD corrections are computed for the process pp -> e+ ve mu- vm~ b b~ j + X.
• This calculation provides the first complete description, which overcomes the narrow width approximation for ttj process in the dilepton decay channel.
