Title: Hunting for the Higgs Boson and more at the LHC

Speaker: Dr. Peter Jenni (Former ATLAS Collaboration Spokesperson，CERN)

Host: Dr. WANG Yifang

Time: 10:00AM, April 18, 2012

Place: Room C305, IHEP Main Building

Abstract:

Since two years experiments at the Large Hadron Collider (LHC) have started exploring the physics at the high energy frontier. A rich harvest of initial physics results has been obtained by the ATLAS Collaboration, which includes a strong team from IHEP Beijing, that allow one already to test, at highest energies ever reached in a laboratory, the Standard Model (SM) of elementary particles, and to make searches Beyond the SM (BSM). Significant results have already been obtained in searches for the Higgs Boson, which would establish the postulated electro-weak symmetry breaking mechanism in the SM, as well as for BSM physics like Supersymmetry (SUSY), Extra Dimensions, production of new heavy particles and others. The status of these searches, and the future prospects at the LHC, will be covered in this talk.

About the speaker:

Peter Jenni, Swiss, borne in 1948, obtained his Diploma for Physics at the University of Berne in 1973 and his Doctorate at the Swiss Federal Institute of Technology in Zürich (ETHZ) in 1976. He participated in CERN experiments at the Synchro-Cyclotron (SC, 1972/3), at the Proton Synchrotron (PS, 1974/6), and as ETHZ Research Associate at the Intersecting Storage Rings (ISR, 1976/7). During 1978/9, he was a Research Associate at the Stanford Linear Accelerator Centre (SLAC), USA, participating in the MARK II experiment at the e+e– storage ring SPEAR. He became a CERN staff in 1980 with the UA2 experiment at the SPS collider (major involvement in the discoveries of jets and the W/Z bosons). His strong interest was with the Large Hadron Collider (LHC) since the beginning in 1984. From 1991 the main activities concentrated on tasks related to the informal spokespersonship first of a proto-Collaboration (Expression of Interest, 1992), and then, on the shared informal spokespersonship with F. Dydak of the ATLAS Collaboration (Letter of Intent 1992, Technical Proposal 1994). In 1995, after formal approval of the project, he was elected Spokesperson of ATLAS which today comprises some 3000 scientists representing 176 Institutions from 38 countries. He was re-elected several times and retired from this duty in February 2009, retaining a strong involvement in the operation and physics of the experiment.

He has served on, and still is member of, numerous international science advisory committees.
