Photon Physics at the LHC - A Measurement of Inclusive Isolated Prompt Photon Production at s = 7 TeV with the ATLAS Detector

This thesis reports on the first studies of Standard Model photon production at the Large Hadron Collider (LHC) using
the ATLAS detector. Standard Model photon production is a large background in the search for Higgs bosons decaying into
photon pairs, and is thus critical to understand. The thesis explains the techniques used to reconstruct and identify
photon candidates using the ATLAS detector, and describes a measurement of the production cross section for isolated
prompt photons. The thesis also describes a search for the Higgs boson in which the analysis techniques used in the
measurement are exploited to reduce and estimate non-prompt backgrounds in diphoton events.
