Hadron-hadron collision mode in ReneSANCe-v1.3.0

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 $pp[p\bar{p}] \to ZX \to \ell^+\ell^- X$, $pp[p\bar{p}] \to W^+X \to \ell^+ν_\ell X$ and $pp[p\bar{p}] \to W^-X \to \ell^-\barν_\ell X$. 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.

Electroweak effects in $e^+ e^- \to Z H$ process

Electroweak radiative corrections to the cross section of the process $e^+ e^- \to Z H$ are considered. The complete one-loop electroweak radiative corrections are evaluated with the help of the SANC system. Higher-order contributions of the initial state radiation are computed in the QED structure function formalism. Numerical results are produced by a new version of the ReneSANCe event generator and MCSANCee integrator for the conditions of future electron-positron colliders. The resulting theoretical uncertainty in the description of this process is estimated.

Polarized NLO EW $e^+e^-$ cross section calculations with ReneSANCe-v1.0.0

In this paper we present a new Monte Carlo event generator ReneSANCe for simulation of processes at electron-positron colliders. In the current release of the generator the Bhabha scattering ($e^+e^- \to e^-e^+$) and Higgs-strahlung ($e^+e^- \to ZH$) process are implemented. Based on the SANC (Support for Analytic and Numeric Calculations for experiments at colliders) modules, the new generator takes into account complete one-loop and some higher-order electroweak radiative corrections with finite particle masses and polarizations. The new generator effectively operates in the collinear region and at the $ZH$ production threshold. It 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 manual.
