A Software Suite for Testing the Performance of the Optical Trigger Motherboard Electronics System for the CMS Experiment at the LHC
(2013-09-28)The Optical Trigger Mother Board (OTMB) and mezzanine card is part of the upgrade of the muon Level-1 trigger system of the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC). 72 of the new boards ... -
A Test Stand for the Muon Trigger Development for the CMS Experiment at the LHC
(2013-05-02)Compact Muon Solenoid (CMS) is one of the flagship experiments in particle physics operating at the Large Hadron Collider (LHC). CMS was built to search for signatures of Higgs bosons, supersymmetry, and other new phenomena. ... -
Efficiency Measurement of Momentum Imbalance Trigger at CMS for Supersymmetry Searches
(2013-02-01)In searches for new fundamental particles in high energy particle collisions, the ability for a detector to select collisions that might signify the presence of such particles is one of the top priorities. Equally important ... -
Neutralinos and Sleptons at the LHC in Light of Muon Anomalous Magnetic Moment
(2016-07-29)We study the possibility of detection of the neutralinos and sleptons of the minimal supersymmetric standard model (MSSM) that explains the (g − 2)µ anomaly at the LHC. In this thesis, we scan the MSSM parameter space that ... -
Real-Time Data Quality Monitoring System for the CMS Muon GEM Detector at the LHC
The new operational conditions associated with the high luminosity upgrade of the Large Hadron Collider (LHC) at CERN requires an upgrade of the muon system in the forward region of the Compact Muon Solenoid (CMS) detector. ... -
Search for New Heavy Resonances Decaying To t+t^- Pairs at the LHC with Square Root S= 7 TEV (L = 5.0 FB^-1)
(2015-01-22)The Standard Model (SM) describes the known fundamental particles and their interactions due to the electromagnetic, weak, and strong forces through vector boson exchange. Although the SM has had major success in predicting ... -
Search for New Light Bosons in Higgs Boson Decays
(2016-08-09)The Standard Model (SM) of particle physics is a theory that summarizes our current knowledge about the most fundamental constituents of matter and interactions between them. The Higgs boson is a central part of the SM as ... -
Search for Supersymmetry in the Jets + Met + TAUS Final State Using the CMS Detector at the LHC
(2013-02-28)In this dissertation results are presented from a search for the pair production of heavy colored particles (gluinos, squarks) in R-parity conserving supersymmetric models, in which the lightest supersymmetric particle is ... -
Search for Supersymmetry Using Weak Boson Fusion Processes in Proton-Proton Collisions at the Large Hadron Collider
(2014-08-08)In 2012, the Large Hadron Collider at CERN (LHC) collided protons at an unprecedented center-of-mass energy of 8 TeV. With data corresponding to a total integrated luminosity of 19.7 fb^(−1), the Compact Muon Solenoid (CMS) ... -
Search for the 125 GeV Standard Model Higgs Boson Decaying Via H→WW→lνjj at √s = 8 TeV
(2018-04-02)The Higgs boson discovery was announced on July 4th, 2012. It was measured to have a mass of 125.7 ± 0.3 (stat) ± 0.3 (syst) GeV and since then boson has been seen in many decay paths, including the H→γγ, H→ZZ→4l, H→τ τ, ... -
Searching for Top Squarks at the Large Hadron Collider
(2014-08-01)This dissertation describes the search strategies we developed for the lighter top squark (called stop, or ˜t) at the Large Hadron Collider (LHC). When the lighter top squarks are produced from the cascade decay of gluino ... -
The F-SU(5) Model with Various Supersymmetry Breaking Soft Terms
(2017-07-24)The flipped SU(5) grand unification model with additional vector-like multiplets (FSU(5)) in the framework of General No-scale Supergravity is studied. The highly constrained soft supersymmetry breaking terms of the ... -
Thermal charm production in a quark-gluon plasma in Pb-Pb collisions at root S(NN)=5.5 TeV
(American Physical Society, 2008)Charm production from the quark-gluon plasma created in the midrapidity of central heavy ion collisions at the Large Hadron Collider (LHC) is studied in the next-to-leading order in QCD. Using a schematic longitudinally ...
