Simulating Particle Colliders

Dr Stefan Prestel, SLAC National Accelerator Laboratory,

High energy particle colliders like the Large Hadron Collider (LHC) provide unique opportunities to study the fundamental laws of physics. With ever increasing energy – the LHC has just restarted with an impressive 13 Tera-Electronvolt collision energy – we hope to discover new phenomena that help resolve core puzzles of particle physics.

Detailed and accurate simulations of "expected" as well as "unexpected" phenomena are necessary to take advantage of the wealth of LHC data, and to guide us towards discoveries.The recent discovery of the Higgs boson is one example of how particle theorists and experimentalists work together to find new phenomena hidden in experimental data.

This talk will give an introduction to how scattering events at high energy particle colliders are calculated, with some emphasis on an accurate modelling of the strong nuclear force. Effects of the strong force are ubiquitous at
particle colliders, and a detailed understanding of Quantum Chromodynamics (QCD) – the theory of strong nuclear interactions – is mandatory for a successful LHC program.
