Updated results from CMS on the new boson discovered at the LHC

Il giorno 17 maggio, alle ore 11, in aula multimediale, il dr. Jim Olsen (Princeton University) terra' un seminario dal titolo: "Updated results from CMS on the new boson discovered at the LHC"

Abstract: On July 4 the CMS and ATLAS experiments operating at the Large Hadron Collider (LHC) near Geneva, Switzerland, announced the discovery of a new particle with a mass near 125 GeV. Very recent results from the CMS experiment using the full dataset from 2012 indicate that the new particle is consistent with the scalar (spin 0 and positive parity) hypothesis, and that it does decay to fermions as well as bosons. It is therefore highly likely to be a Higgs boson, but the exact nature of this particle will require additional data to ascertain. In this seminar I will present a summary of the recent results from the CMS experiment on the nature of this new boson.
