Abstract
This chapter gives an overview of basic accelerator concepts helpful for understanding the LHC and the dataset used in this analysis. It motivates the design choices of the LHC, describes how a collision energy of 13 TeV is achieved and typical operating parameters. The luminosity of the LHC is also discussed, along with how it translates to the number of possible events of a given process and to pileup.

Notes
- 1.
If the magnets were not superconducting, the LHC would need to be an order of magnitude larger, 127km, in order to reach the same energy.
- 2.
In fact, extra sea quarks come in and out of existence inside of the protons, these take energy from the main valence quarks and can be collide.
- 3.
If the magnets were not superconducting, the LHC would need to be an order of magnitude larger, 127 km, in order to reach the same energy.
- 4.
Run 1 took place from 2009–2013 with a center of mass energy of 7 TeV and resulted in 27 fb−1 of data. This is the run in which the Higgs boson was discovered. Run 1 data is not used in this analysis.
