Exotic Higgs searches at LHC

After the discovery in 2012 of a particle consistent with the Higgs boson predicted by the Standard Model, a rich physics plan has been undertaken by the ATLAS and CMS collaborations to better explore the Higgs sector. While the Higgs mechanism provides an explanation for the origin of the masses of fundamental particles, it can be used to probe several possible extensions of the SM. In many cases, the signatures that indicate the presence of new physics have no equivalent in the Higgs sector of the SM, and are usually referred to as exotic. These studies can shed light on several BSM theories: from supersymmetry to dark matter, from neutrino mass generation to the presence of extra dimensions. I will review the status of these searches at LHC experiments and describe the future prospects of this physics program.


About the speaker:
Mario Pelliccioni is currently a professor of Physics at INFN Torino, Itlay. Mario obtained his PhD in Turin in 2008, with a thesis on one of the first evidences of charm flavor oscillation at BaBar. In 2009 he joined the CMS collaboration, working on muon detectors and L1 trigger. He worked on the first search at LHC for a light pseudoscalar Higgs boson in the dimuon invariant mass spectrum, and on the H to ZZ to 4l analysis. He participated in the 2012 discovery of the Higgs boson. Since then, he has been working on the search for additional Higgs bosons. He has been a convener of several physics analysis groups at the CMS such as the “Exotic Higgs" searches working group, “BSM Higgs" working group, and of the "LHC Higgs CrossSection" Working Group.
