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.

Study of beam-halo events in photon production in the CMS experiment
Yıldırım, Eda; Güler, Ali Murat; Department of Physics (2011)
The Compact Muon Solenoid (CMS) Experiment operates at the Large Hadron Collider (LHC) which is the highest energy particle accelerator in the world. CMS is a general purpose detector designed to investigate a wide range of physics, including the search for the Higgs boson. The measurement of photon production in the CMS experiment is crucial since it represents an irreducible background for many new physics searches, such as decay of Higgs to two photon, supersymmetry and extra-dimensions. The study of bea...
Combined search for the Standard Model Higgs boson in pp collisions at ffiffiffi root s=7 TeV with the ATLAS detector
Aad, G.; et. al. (2012-08-02)
A combined search for the Standard Model Higgs boson with the ATLAS detector at the LHC is presented. The data sets used correspond to integrated luminosities from 4.6 fb(-1) to 4.9 fb(-1) of proton-proton collisions collected at root s = 7 TeV in 2011. The Higgs boson mass ranges of 111.4 GeV to 116.6 GeV, 119.4 GeV to 122.1 GeV, and 129.2 GeV to 541 GeVare excluded at the 95% confidence level, while the range 120 GeV to 560 GeV is expected to be excluded in the absence of a signal. An excess of events is ...
Search for Z’ via forward backward asymmetry in dielectron channel with the CMS detector at the large hadron collider
Şahin, Mehmet Özgür; Serin, Meltem; Zeyrek, Mehmet Tevfik; Department of Physics (2012)
In this thesis, analysis of the forward backward asymmetry of high energy electron pairs at the CMS - LHC with a centre of mass energy of 7 TeV is presented and the possibility of search for a new neutral weak boson Z’ via measuring the forward backward asymmetry AFB of high energy electron pairs is discussed. The forward backward asymmetry is a natural result of the interference between the neutral current mediators: Photon and Z boson. A new neutral gauge boson would also interfere with these mediators an...
Searches for supersymmetry at the high-luminosity LHC
Yeşilyurt, Gökçenur; Serin, Meltem; Çakır, Muammer Altan; Department of Physics (2018)
High Luminosity LHC (HL-LHC) project is an upgraded version of the LHC that enables to explore beyond the Standard Model theories and is expected to exceed the limits of currently conducted experiments. Supersymmetry is one of the commonly used and well-known beyond the Standard Model theories proposing a symmetry with brand-new particles and by doing so, bringing solutions to the unsolved zones that the Standard Model is not available to reach. In this thesis, by considering the high luminosity and the cen...
Measurement of chi(c1) and chi(c2) production with root s=7 TeV pp collisions at ATLAS
Aad, G.; et. al. (2014-07-01)
The prompt and non-prompt production cross-sections for the chi(c1) and chi(c2) charmonium states are measured in pp collisions at root s = 7TeV with the ATLAS detector at the LHC using 4.5 fb(-1) of integrated luminosity. The chi(c) states are reconstructed through the radiative decay chi c -> J/psi gamma ( with J/psi -> mu(+)mu(-)) where photons are reconstructed from gamma -> e(+)e(-) conversions. The production rate of the chi(c2) state relative to the chi(c1) state is measured for prompt and non-prompt...
