Update of the MCSANC Monte Carlo integrator, v. 1.20

New features of the MCSANC v.1.20 program, a Monte Carlo tool for calculation of the next-to-leading order electroweak and QCD corrections to various Standard Model processes, have been presented. The extensions concern implementation of Drell-Yan-like processes and include a systematic treatment of the photon-induced contribution in proton-proton collisions and electroweak corrections beyond the NLO approximation. There are also technical improvements such as calculation of the forward-backward asymmetry for the neutral current Drell-Yan process. The updated code is suitable for studies of the effects due to EW and QCD radiative corrections to Drell-Yan (and several other) processes at the LHC and for forthcoming high-energy proton-proton colliders.
