The 20th Hadron Collider Physics Symposium in Evian

The Hadron Collider Physics Symposium series has been a major forum for presentations of physics at the Tevatron over the past two decades. The merger of the former Topical Conference on Hadron Collider Physics with the LHC Symposium in 2005 brought together the Tevatron and LHC communities in a single forum.
The 20th Hadron Collider Physics Symposium took place in Evian, on the shores of Lake Geneva, from 16-20 November 2009, some 17 years after the historic ECFA-CERN Evian meeting in March 1992 when Expressions of Interest for LHC detectors were presented for the first time. The 2009 event was organized jointly by CERN and the French high-energy physics community (CNRS-IN2P3 and CEA-IRFU). More than 170 people registered for this symposium.

This year’s symposium was held at an important time for both the Tevatron and the LHC. It stimulated the completion of analyses for a significant Tevatron data sample, and it allowed an in-depth review of the readiness of the LHC and its experiments just before first collisions. The programme included sessions on top-quark and electro-weak physics, QCD, B physics, new phenomena, electro-weak symmetry breaking, heavy ions, and the status of the Tevatron and LHC machines and their experiments. Many new Tevatron results were presented for the first time, including an update on the Higgs search. The sessions were supported by excellent theoretical overviews. The Symposium ended with an outlook on future developments for the Tevatron and the LHC as well as physics road-maps and plans for the regions of Asia, Europe and North America.

The 21st Hadron Collider Symposium will be held in Toronto, Canada, from 23 to 27 August 2010, and the high-energy physics community is looking forward to results from the first physics runs at the LHC and the latest results from the Tevatron. Future events are also planned for Paris in 2011 and Japan in 2012.

The organizing committee would like to thank all the participants for their important contributions to the symposium as well as the sponsors – CERN, IRFU/CEA, IN2P3/CNRS, the Rhone-Alps region and the Universities of Grenoble and Savoie. The town of Evian also kindly participated in the organization.
