At the Brink of Discovery- High-Energy Physics Discoveries: From the Tevatron to the Large Hadron Collider
AAAS 09 Symposium
Maria Spiropulu, CERN, Geneva, Switzerland; Joseph Lykken FNAL, Chicago IL, US
The very-high-energy proton-antiproton collisions at the Tevatron and proton-proton collisions at the Large Hadron Collider (LHC) are meant to dissect matter and space-time itself into its primary elements and generators. The experiments at the Tevatron and the LHC by synthesizing the information from the debris of the collisions are reconstituting the interactions that took place. The experiments at the Tevatron and the LHC are at the closest point of addressing in the lab some of the most puzzling fundamental observations in nature today such as the dark matter of the universe. This symposium will review the results from the Tevatron's largest-ever hadron collision data sets as the frontier energy baton is being passed to the LHC, the machine of unprecedented scale and complexity that will determine the future of the discipline of high-energy physics. The LHC starts operation in the summer of 2008, and the symposium will report on the machine and the two general purpose experiments, A Toroidal LHC ApparatuS (ATLAS) and the Compact Muon Solenoid (CMS).

Director, Fermi National Accelerator Laboratory
Pier Oddone was appointed the director of Fermi National Accelerator Laboratory in July 2005. Fermilab, a U.S. Department of Energy national laboratory, advances the understanding of matter, energy, space and time through the study of elementary particle physics and particle astrophysics. The laboratory is managed by the Fermi Research Alliance, a partnership of the University of Chicago and the Universities Research Association. Oddone previously served as deputy director of DOE's Lawrence Berkeley National Laboratory, with primary responsibility for the scientific development of the laboratory and its representation to the agencies. He received the 2005 Panofsky Award of the American Physical Society for the invention of the Asymmetric B-Factory. He is a Fellow of the American Physical Society, and was elected as Fellow of the American Academy of Arts & Sciences in 2008. Oddone was born in Arequipa, Peru, and is a U.S. citizen. He received his Ph.D. in Physics from Princeton University.
Jacobo Konigsberg is a professor of physics at the University of Florida, Gainesville, and cospokesperson of the CDF experiment at Fermi National Accelerator Laboratory. CDF is a collaboration of more than 600 physicists from 65 institutions from 15 countries. The experiment studies proton-antiproton collisions produced by the Tevatron accelerator at Fermilab. Research at CDF includes the search for the Higgs particle and other physics phenomena beyond the standard model of particles and fields. Konigsberg was part of the team that discovered the top quark at CDF and his research is centered on elucidating the properties of this particle and its possible connections to new physics. He participated in the construction and operation of various CDF detector systems and has held leadership positions of various physics analysis groups. He received his Ph.D. from UCLA, working on an experiment at Brookhaven National Laboratory. He received the 2004 medal of the Division of Particles and Fields of the Mexican Physical Society and is a member of the Mexican Academy of Sciences and elected Fellow of the Americal Physical Society.
Dmitri Denisov is staff scientist and the cospokesperson of the DZero experiment at Fermi National Accelerator Laboratory. His research includes studies of interactions of particles and nuclei, the search for new particles and forces at the energy frontier, and the development of new detectors and experimental methods for nuclear and elementary particle experiments. Denisov received his doctoral degree from the Institute for High Energy Physics at Serpukhov. In the 1990s, he was leader of design and construction of major elements of the DZero experiment. He was a member of the DZero team that discovered the top quark in 1995. As DZero cospokesperson, Denisov leads a collaboration of 600 physicists from 18 countries. Under his leadership, the DZero collaboration made multiple fundamental discoveries such as finding evidence for single top quark production, the observation of the Cascade and Omega baryons and the first observation of pair production of Z bosons, a critical milestone on the road to observing the elusive Higgs boson.
Lyn Evans is recognized worldwide as an outstanding expert in particle accelerators. He was elected a Fellow of the American Physical Society "for contributions to the physics of particle accelerators and storage rings, in particular to the development of the understanding of the fundamental limitations of high-energy hadron colliding beam devices." Evans has worked at the forefront of the development of the world's most powerful accelerators for more than 30 years. Since 1994, he has led the design and construction of the Large Hadron Collider at CERN, the European Laboratory for Particle Physics near Geneva, Switzerland. The LHC will advance the energy frontier and allow scientists to search for new physics phenomena such as the Higgs particle, supersymmetric particles and extra dimensions.
Marzio Nessi is the technical coordinator (project manager) of the ATLAS experiment at the CERN Large Hadron Collider. He earned his Ph.D. in physics from ETH Zurich, Switzerland. As a research staff member at Rice University, he worked on experiments at Brookhaven National Laboratory, at Fermilab and at CERN. Since 1989, he has worked at CERN, where he took part in the running and physics analysis of the UA2 experiment. He joined the ATLAS project at its very beginning and worked on the core effort that led to the design and the scientific and technical proposals for the ATLAS experiment at LHC. He was the spokesman of the RD34 project for ATLAS, and then became project leader of the ATLAS hadron tile calorimeter, which he had conceived. In 1999, he was elected by the ATLAS scientific collaboration as the overall technical coordinator. In this position he has led the successful construction of the gigantic ATLAS detector, which saw its first beam in September 2008.
Tejinder (Jim) Virdee is professor of physics at Imperial College, London and scientific associate at CERN. He is the spokesperson of the Compact Muon Solenoid collaboration at the CERN Large Hadron Collider and was the deputy spokesperson of CMS from 1993 to 2006. Virdee's graduate studies at Imperial College were on an experiment conducted at the Stanford Linear Accelerator Center. He worked on a deep inelastic Compton scattering experiment and then on the UA1 proton-antiproton collider experiment, both at CERN. Since 1990, Virdee has concentrated on the physics of, and experimentation at, the next generation of hadron colliders. He is a founding member of the CMS collaboration, which now comprises over 2500 scientists and engineers from over 180 institutes in about 40 countries, including the UK. Virdee has been actively involved in all phases of the CMS experiment, including the definition of the physics goals; detector R&D and prototyping; construction, installation, and commissioning of the detector; and the preparations for the extraction of science results. CMS performed well when the first beams traversed the detector in September 2008.
