Higgs Properties and BSM Search in 4 lepton channel at ATLAS

Panagiotis Bellos (Birmingham University)


The discovery of Higgs boson in 2012 by the ATLAS and CMS experiments marked a key milestone in the history of particle physics. The H->ZZ*->4l channel had a great contribution in this discovery. Currently many physics analyses are being carried out in this channel. In this seminar, firstly, the event selection and the background estimation will be discussed. Next, the latest results from the Run II analyses will be presented, including the mass, width and cross section measurements, as long as the search for a Beyond the Standard Model heavy Higgs boson.
