mcsanc is a Monte Carlo tool based on the SANC (Support for Analytic and Numeric Calculations for experiments at colliders) modules for higher order calculations in hadron collider physics. It allows to evaluate NLO QCD and EW cross sections for Drell–Yan processes (inclusive), associated Higgs and gauge boson production and single-top quark production in s- and t-channels. The paper contains theoretical description of the SANC approach, numerical validations and manual. Program title: mcsanc-v1.01 Catalogue identifier: AEPO_v1_0 Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AEPO_v1_0.html Program obtainable from: CPC Program Library, Queen’s University, Belfast, N. Ireland Licensing provisions: Standard CPC licence, http://cpc.cs.qub.ac.uk/licence/licence.html No. of lines in distributed program, including test data, etc.: 144207 No. of bytes in distributed program, including test data, etc.: 1115648 Distribution format: tar.gz Programming language: Fortran, C, C++. Computer: x86(-64) architecture. Operating system: Linux. RAM: 2 GB Classification: 11.1, 11.6. External routines: LHAPDF [1]. LoopTools [2], Cuba [3] (included in the distribution file). Nature of problem: Theoretical calculations at next-to-leading order in perturbation theory allow the computation of higher precision amplitudes for Standard Model processes and decays, provided proper treatments of UV divergences and IR singularities are performed. Solution method: Numerical integration of the precomputed differential expressions for partonic cross sections of certain processes implemented as SANC modules [4]. Restrictions: The list of processes is limited to Drell–Yan, associated Higgs and gauge boson production and single-top production in s- and t-channels. Running time: From hours to days depending on the requested precision and kinematic conditions. The example provided takes approximately 10–15 min. References:[1]M.R. Whalley, D. Bourilkov, and R.C.
