The long journey to the Higgs boson and beyond at the LHC
Abstract
Since three years the experiments at the Large Hadron Collider
(LHC), in particular ATLAS, investigate particle physics at the
highest collision energies ever achieved in a laboratory. Following a
rich harvest of results for Standard Model (SM) Physics came in 2012
the first spectacular discovery of a new, heavy particle, most likely
the long-awaited Higgs boson. The latest results with the full data
set accumulated over the first three-years running period of the LHC
will be presented. Other, far-reaching results can already be reported
for exploratory new physics searches like Supersymmetry (SUSY) and its
implication for Dark Matter in the Universe, Extra Dimensions, and the
production of new heavy particles.
However, with the recent discovery of a new boson the exciting
journey into unexplored physics territory, within and beyond the SM,
has only just begun at the LHC, in particular also in view of the
increased collision energy expected for the next running period
starting in 2015. Besides the first results and the future prospects,
the talk will also cover briefly the history and the challenges of the
whole LHC project, as well as the fruitful collaboration with the Lund
University and the other Swedish groups since the very beginning of
this large scientific adventure.
Peter Jenni, Swiss, borne in 1948, obtained his Diploma for
Physics at the University of Bern in 1973 and his Doctorate at the
Swiss Federal Institute of Technology in Zürich (ETHZ) in 1976.
Peter Jenni participated in CERN experiments at the
Synchro-Cyclotron (1972/3), at the Proton Synchrotron (1974/6), and as
ETHZ Research Associate at the Intersecting Storage Rings (1976/7),
the first high-energy hadron collider. During 1978/9, he was a
Research Associate at the Stanford Linear Accelerator Centre (SLAC),
USA. He became a CERN staff in 1980 with the UA2 experiment at the
SPScollider (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. In 1995, after formal approval of the ATLAS
project, he was elected Spokesperson of the experiment, which today
comprises some 3000 scientists representing 177 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. In particular, over the last 18 months he
was strongly involved in shaping the scientific input with the
Preparatory Group for the Update of the European Strategy for Particle
Physics, personally motivated to promote CERN’s future at the high
energy frontier.
After his retirement as a CERN Senior Research Staff end of April
2013, Peter Jenni has become a Guest Scientist with the
Albert-Ludwigs-University Freiburg, Germany, keeping his full
engagement with the ATLAS experiment.
He received (or shared) among others the Swiss Greinacher Prize in
1998, the Slovak gold medal of the Comenius University in 1999, the
Czech Charles University memorial silver medal in 2001, the Czech
Academy of Sciences Ernst Mach Honorary Medal in 2012, and in 2013 the
German Julius Wess Award, a share of the Special Fundamental Physics
Prize (FPP), and a share of the High Energy and Particle Physics Prize
of the European Physical Society (EPS).
