Measurement of Top-Quark Pair Production Cross Sections and Calibration of the Top-Quark Monte-Carlo Mass using LHC Run I Proton-Proton Collision Data at square $\sqrt{s}= 7 and 8 TeV with the CMS Experiment. / Kieseler, Jan (DESY) ; Lipka, Ekaterina (dir.) (DESY)
In this thesis, measurements of the production cross sections for top-quark pairs andthe determination of the top-quark mass are presented. Dileptonic decays of top-quarkpairs (tt) with two opposite-charged lepton (electron and muon) candidates in the finalstate are considered. [...]

Search for New Light Higgs Bosons in Boosted Tau Final States with the CMS Experiment / Ricci-Tam, Francesca
In this dissertation, I present a search for non-standard decays of a Standard Model-likeHiggs boson to pairs of light bosons, as predicted in models with extended Higgs sectors.In two Higgs doublet models, including the next-to-minimal supersymmetric standardmodel, the Higgs boson can decay into a [...]

Search for Anomalous Single Top Quark Production in Association with a Photon in pp Collisions at $\sqrt{s}$ = 8 TeV / Goldouzian, Reza (Brussels U.) ; Mohammadi Najafabadi, Mojtaba (dir.) (IPM, Tehran)
This thesis reports the results of a first search for the flavor-changing neutral current(FCNC) through the anomalous production of single top quark in association witha photon due to the anomalous interactions of tqγ (q = u or c) in pp collisions. Thissearch is performed using 19.8 fb−1 of data collected with the CMS detector at thecenter-of-mass energy of 8 TeV.In this study we only concentrate on the muonic decay of the W-boson in topquark decay [...]
