Validation of Particle Physics Simulation

The procedures of validating computer simulations of particle physics events at the LHC are summarized. Because of the strongly fluctuating particle content of LHC events and detector interactions, particle-based Monte Carlo methods are an indispensable tool for data analysis. Simulation in particle physics is founded on factorization and thus its global validation can be realized by validating each individual step in the simulation. This can be accomplished by drawing on results of previous measurements, in situ studies, and models. What is particularly important in particle physics is to quantify how well a simulation is validated such that a systematic uncertainty can be assigned to a measurement. The simulation is tested for a wide range of processes and agrees with data within the assigned uncertainties.

I am grateful to Martin King and Michael Stöltzner and anonymous referees for valuable comments. I also profited highly from discussions with colleagues from the Research Group “Epistemology of the LHC” funded by the DFG under grant FOR 2063.
