Description
Monte Carlo event generators aim to provide a full description of high-energy collisions with hundreds of final state particles which requires physics modelling at various energy scales. The event generation typically begins by sampling the particles created in the primary hard scattering process of interest. The radiation from these high-virtual particles, can then be modelled with parton showers which explicitly generates each emission and evolve the partons down to non-perturbative energy scales. At this point, a hadronization model is employed to convert the partonic configuration into a hadronic one. These primary hadrons then may decay into stable hadrons with long-enough lifetime to be seen in particle detectors.
In this talk I will a give a brief introduction to the physics modelling in modern event generators and highlight some recent developments and precision improvements relevant to hadronic collisions at the LHC. Then I outline the scattering processes accessible at the EIC and discuss event generator requirements for such processes. As a last point I will highlight a few recent LHC measurements which provide novel constraints for photon-mediated scattering processes at the EIC.
