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 Z boson decaying into an electron and a muon. Evidence of this decay would be the first sign of a Flavor Changing Neutral Current for charged leptons and direct evidence for physics beyond the Standard Model. The second analysis presents a measurement of the differential cross section $d\sigma/d\phi^{\star}$ for Z decaying into two muon events. The $\phi^\star$ variable is a novel approach to measuring the transverse momentum of the Z boson using only the angular variables of the two muons. This cross section is compared to the \Py and \mad MC generators.
