Description:: Since its discovery in 2012 at the Large Hadron Collider (LHC), efforts have beenmade to measure and characterize the properties of the Higgs boson. Among these efforts have been searches for rare decays of the Higgs predicted by the standard model (SM) of particle physics. One such decay is the...

Description:: The leptonic and inclusive hadronic decay branching fractions of the W boson are studied using 35.9 $fb^{-1}$ of proton-proton collision data collected at $\sqrt{s}=13~TeV$ during the 2016 run of the CMS experiment. Events characterized by the production of pairs of W bosons from \ttbar and \tW processes are selected. Multiple...

Description:: The pp → W + W − process is important as it allows the test of electroweak theory. Mea-surements of this processes have lead to reduced uncertainties on many other processes one of which being the Higgs. There have been discrepancies between predicted and measured cross-section values for pp →...

Description:: In 2012 the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) collected 19.7 fb-1of data at a center of mass energy of 8 TeV. This thesis presents two analyses focusing on the Z boson. The first is a search for the never before seen decay of a...
