Search for Supersymmetric Top-Quark Partners Using Support Vector Machines and Upgrade of the Hadron Calorimeter Front-End Readout Control System at CMS [DESY-THESIS-2017-014] DESY-THESIS 171 pp., (2017) [10.3204/PUBDB-2017-01744]   In this thesis a search for direct pair production of supersymmetric top-quark partners as well as work on the upgrade of the front-end readout controller of the Hadron Calorimeter (HCAL) of the Compact Muon Solenoid (CMS) experiment are presented. The most appealing extension of the Standard Model (SM) is supersymmetry (SUSY), relating the integer spin (bosons) and half-integer spin elementary particles (fermions).

Charm Production and QCD Analysis at HERA and LHC [DESY-17-025; arXiv:1612.02371] This review is devoted to the study of charm production in ep and pp collisions. The total set of measurements obtained by the two collaborations H1 and ZEUS from HERA and their combination is outlined, as well as complementary data obtained by the LHCb Collaboration at the LHC.

It uses boosted decision trees to combine information on the global event and jet properties to distinguish between ttbar-ttbar and ttbar production.
