KT.HIP - Higgs Physics with the ATLAS Experiment
This Lab is an example of a data analysis and measurement commonly done in particle physics. You will search for Higgs bosons decaying into two photons in data taken with the ATLAS experiment at the LHC. At first, you will learn about typical kinematic variables used in particle physics and how these can be used to identify signal and background events. Being able to distinguish between signal and background, you will calculate the cross section of Higgs production, where the Higgs boson decays into two photons, based on your observations in ATLAS data. The second task is to develop an event selection optimised for a specific Higgs production mechanism, vector boson fusion, and to calculate the obtained signal significance for this process.
