Abstract
The Large Hadron Collider (or LHC for short) was built to collide protons at a very high center-of-mass energy, in order to test predictions of different theories in particle physics and to confirm the existence of the Higgs boson. For the comparison between experimental data against theory predictions, simulations play a crucial role. In this chapter, we present an overview of both the LHC itself and methods used to simulate events at hadron colliders.

Notes
- 1.
The Tevatron is located at the Fermi National Accelerator Laboratory, and was built to collide protons and anti-protons with a center-of-mass energy limit of approximately 2 TeV. It has worked from 1983 until September of 2011, having many important discoveries on its list of achievements (including the discovery of the top quark in 1995). The large number of breakthroughs made by the Tevatron enabled the proposition of a even stronger particle collider, the LHC.
- 2.
Once a parton is emitted, it can multiply and emit other partons. These are usually soft, or collinear partons, which can be approximately reproduced in perturbation theory. A more precise explanation is given further ahead within this chapter.
