Abstract

We report an implementation of the hadron-hadron ($pp$ and $p\bar{p}$) collision mode to the Monte Carlo event generator ReneSANCe - the code that was previously developed for $e^+e^-$ collisions. The described extension of ReneSANCe currently contains neutral and charged current Drell-Yan prosesses $pp[p\bar{p}] \to ZX \to \ell^+\ell^- X$, $pp[p\bar{p}] \to W^+X \to \ell^+\nu_\ell X$ and $pp[p\bar{p}] \to W^-X \to \ell^-\bar{\nu}_\ell X$. We take into account complete one-loop electroweak (EW) and one-loop QCD corrections to these processes. The calculation is based on the SANC (Support for Analytic and Numeric Calculations for experiments at colliders) modules. The generator is constructed in such a way that new processes can be easily added. The paper contains a theoretical description of the SANC approach, numerical validations and a manual.
