NLO QCD corrections for off-shell $t\bar{t}b\bar{b}$
Abstract
We present a full off-shell NLO QCD calculation of pp \rightarrow e^+ \nu_e b \mu^- \bar{\nu}_\mu \bar{b} b \bar{b} + X pp→e+νebμ−ν‾μb‾bb‾+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 b -quarks and we introduce two b b -jet tagging schemes.
