Description

We present NLOPS matched predictions for $pp\to \ell {\nu }_{\ell }jjb\overline{b}$ at ${\alpha }^4{\alpha }_s^2$ within the POWHEG BOX RES framework. This process is dominated by top-pair production and decay in the semileptonic channel. The hadronic decay of the W-boson is considered in an approximation that allows for consistent inclusion of the contributions from $t\overline{t}$ and $Wt$ single-top production and all relevant quantum interferences between different channels.
