| Abstract: | We present results in the search for the standard model Higgs boson from the CMS experiment in proton-proton collisions at the LHC. An excess of events above the expected background is observed with a significance of five standard deviations, indicating production of a new boson. The excess is strongest in the ZZ(*) and gamma-gamma channels, and the full result includes WW(*), b-bbar, and tau+tau- final states as well. Prospects for testing properties of this new boson are discussed. |
| Speaker: | Andrei Gritsan - Johns Hopkins University
 Professor Gritsan earned his Ph.D. from the University of Colorado, with the observation of the first gluonic penguin decays (B -> eta'K and related modes) at CLEO. He worked on BaBar as a postdoctoral fellow at LBNL and then as a faculty member at Johns Hopkins, concentrating on B decays to two vector mesons or a vector and tensor meson, including the extraction of the CKM angle alpha and the study of the "polarization puzzle". He joined CMS in 2005, and has worked on Higgs, exotic and electroweak physics. He is a convener of the CMS Higgs->ZZ working group and a developer of the MELA (matrix element likelihood analysis) project used both for background suppression and spin/parity measurements in Higgs decays to two vectors.
