Machine learning for particle identification & deep generative models towards fast simulations for the Alice Transition Radiation Detector at CERN
… physics detector simulations are pertinent to research avenues pursued by physicists working with the ALICE (A Large Ion Collider Experiment) Transition Radiation Detector (TRD), within the Large Hadron Collider (LHC) at CERN (The European Organization for Nuclear Research).

Micron precision calibration methods for alignment sensors in particle accelerators
Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, has, on each side of its four experiments, a set of three magnets, called low-beta magnets. These magnets provide the final-focus for the beams that collide head on in the experiments. The magnets have to be …

Studies of the Photoproduction of Charm-Anticharm Resonances in Ultra-Peripheral Collisions of Lead Ions in ALICE at the LHC
The research presented in this thesis was carried out with the ALICE (A Large Ion Collider Experiment) detector at the CERN (European Organization for Nuclear Research) LHC (Large Hadron Collider). Two feasibility studies are conducted for Run 2 energies at the LHC. The first case studies the …

TRANSVERSE MOMENTUM EVOLUTION OF HADRON-V0 CORRELATIONS IN PP COLLISIONS AT 7 TEV
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, is capable of accelerating beams of protons (pp) and heavy-ions (Pb+Pb) up to nearly the speed of light, which corresponds to center of mass energies of 7 TeV and 2.76 TeV, respectively. …

Analysis of petal longterm test data for the CMS-experiment
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva will start end of 2008. One of the experiments at the LHC is the multipurpose detector CMS (Compact Muon Solenoid). A key part of the CMS detector is the tracking system, that is composed of a silicon …

Challenges for copyright holders on the Internet: a Turkish case study
In September 2004, scientists from the California Institute of Technology and the European Organization for Nuclear Research succeeded in sending 859 gigabytes of data from California to Switzerland in less than 17 minutes. At such speed, a full-length feature film can be downloaded in 4 seconds. …

Analysis of 3D silicon pixel vertex detector damage effects due to radiation levels present in the LHC at CERN
… particles that traverse them, but tracking performance begins to deteriorate at fluxes of radiation around 10¹⁴ - 10¹⁵ hadrons/cm 2. These radiation levels are congruent with those experienced by the ATLAS pixel detector, the inner most part of the ATLAS tracking system, which is vital to track …

A search for Z' bosons in the dimuon decay channel in 8 TeV proton-proton collisions
In this thesis, I present a search for $Z'$ bosons in the $\mu^+\mu^-$ decay channel using 20 fb$^{-1}$ of $p$-$p$ collisions at $\sqrt{s} = 8 $ TeV, produced during the 2012 run at the Large Hadron Collider at CERN, using the ATLAS detector to record the collision products. The search proceeds via …

Search for flavor changing neutral currents in top quark decays using a two-leptons+track selection
A search for flavor-changing neutral currents in top quark decays is described. Data collected at a center- of-mass energy of √s = 7 TeV during 2011 corresponding to an integrated luminosity of 2.1 fb^{-1} are used. A cut-based analysis is used on top quark pair production events, where one top …
