Description:: This thesis focuses on exploring the explanatory and discovery potential of the four-neutrino and enhanced neutrino magnetic and electric dipole moments hypotheses when applied to the NOvA/T2K discrepancy and the XENON1T anomaly, respectively. Firstly, we study the effect of a very light (sub eV) sterile neutrino on the NOvA/T2K anom-...

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...
