Study of misalignment effects in the CMS forward hadron calorimeter

Kılınç, Cemali
The Compact Muon Selonoid (CMS) is a general purpose detector at the Large Hadron Collider (LHC). It is designed to investigate a wide range of physics, including the search for the Higgs boson and physics beyond the Standard Model. The CMS detector consists of various sub-detector systems, measuring energy, momentum, charge and trajectory of the particles produced by the proton-proton collision in the detector. The Forward Hadron Calorimeter (HF), a sub-system of Hadron Calorimeter (HCAL), identi es and measures the forward jets. It is designed as a rotational symmetric with respect to collision point. This leads total energy deposition to be symmetric in azimuthal direction (φ). Energy response of the readout channels are calibrated by using φ symmetry. However, misalignment of the HF breaks this symmetry. This study, simulation-based, focuses on the variations in the readouts geometry and total energy deposition due to misalignment of the HF. Moreover, the relation between geometry and total energy deposition is also studied.
