Description
We are pleased to announce that an ICFA mini-workshop on "Beam-Beam Effects in Hadron Colliders" will be held at CERN in Geneva, Switzerland from March 18th to 22nd, 2013. This workshop is a successor and follow up to similar workshops held at CERN in April 1999 and at Fermilab in June 2001. It is motivated by the successful start of the LHC and the emergence of a vast amount of beam-beam observations. We feel the need to review the progress made since the last workshop on beam-beam effects. The purpose of this workshop is to review the present knowledge and compare with the observations, and to discuss and plan future research work, with special emphasis on the performance of the LHC after the first long shutdown as well as on studies needed for the planned LHC upgrade projects such as HL-LHC and LHeC.
