Description

Monte Carlo event generator tuning is essential for the accurate modeling of proton-proton collisions in the CMS experiment. Commonly used generators such as Pythia and Herwig rely on phenomenological models of the underlying event, including multiparton interactions, as well as color reconnection and other non-perturbative QCD components, whose parameters must be constrained using data. This talk presents an overview of how generator tuning is performed in CMS, highlighting key inputs, methodologies, and results.
