NLO QCD corrections for off-shell ttbb
Abstract
We present a full off-shell NLO QCD calculation of pp → e+ e b μ- μ b b b + X. Results are obtained using the HELAC-NLO Monte Carlo framework. We discuss a comparison to previous results and to experimental measurements. We also investigate the contribution of the initial states involving b-quarks and we introduce two b-jet tagging schemes.
