Search for Charged Higgs Bosons at centre-of-mass Energies of 189-209 GeV at LEP
In dieser Arbeit wird eine Suche nach geladenen Higgs Bosonen an dem Large Electron and Positron Speicherring (LEP) am CERN praesentiert. Es wurde speziell der Zerfall des geladenen Higgs Bosons (H^+/-) in ein CP-ungerades Higgs Boson (A^0) und ein virtuelles W Boson (W^*), am OPAL Detektor, …

Deep Neural Network Classifiers in CMS Track Reconstruction and in the Search for the Charged Higgs Boson
… the task of rebuilding the flight paths of charged particles called tracks inside the detector using the measurements made by the Tracker sub-detector in the heart of the CMS. The conditions present inside the detector during particle collisions demand for advanced algorithms able to be both …

Search for a charged Higgs Boson in proton-proton collisions at the LHC using the ATLAS detector
This thesis documents several searches for charged Higgs bosons ($H^{\pm}$) in the decay $H^{\pm} \rightarrow \tau_{had} \nu$, which are performed using data recorded in 2011 and 2012 by the ATLAS detector at the LHC. The $H^{\pm}$ bosons are predicted by some extensions of the Standard Model (SM) …

Precision Measurements of the Vector Boson Scattering Production and Searches for Charged Higgs Bosons at the Large Hadron Collider
… in association with two jets and a search for charged Higgs bosons (H superscript ±) decaying into a top and a bottom quark. The data samples used for the measurements are LHC proton-proton collisions recorded with the CMS detector during 2016–2018 at √𝑠 = 13TeV, corresponding to an integrated …

Searches for New Physics at the Large Hadron Collider
… to assess the discovery/exclusion potential of a charged Higgs boson in the Two Higgs Doublet Model using the process pp → tH± followed by the H± → W±A and A → t¯t. This provides the signal tt¯tW± and we study the final states with three leptons and with two leptons of the same charge. It is found …

Observation of electroweak W±W± JJ production with the CMS experiment
… to probe the couplings of the newly discovered Higgs boson to vector bosons. The channel in which the W bosons decay to charged leptons and neutrinos is the most sensitive and is thus the one that is used by the CMS Collaboration for the initial observation of this process. The data that is used …

Probing New Physics Through Third Generation Leptons
… physics or new physics. The third generation charged lepton -the τ -is an excellent probe of new physics (NP) because of it being the heaviest lepton. As the heaviest lepton, it has the largest coupling ( among the leptons) to the Higgs boson in the Standard Model (SM). New physics …

Higgs Effects in Neutrino Physics and Heavy Quark Systems
… work presents a study of the effects of multi-Higgs doublets on the properties of neutrino sector and heavy quark systems. The phenomenological implications of multi-Higgs models, which contain multi-Higgs doublets, in the neutrino and quark sector are discussed in this dissertation. The …

Searching For New Physics In The B-Quark’s And Higgs’ Sectors Via Kinematic And Angular Distributions
… Type II and leptophilic 2HDM’s. Although, the Higgs was found at the LHC in 2012, the question remains whether it is of the SM variety. A MadGraph simulation is performed confirming the dihedral distribution calculation given the experimentally determined uncertainties in the Higgs’ couplings. …
