Description
More than 5 years have passed since the beam-beam community last met to discuss the challenges linked to circular colliders.
As new projects arise with ever increasing expectations, we believe that the time has come for our community to gather again and share the progress in the physics of particle colliders, identify the challenges ahead of us and elaborate a vision to address them.
A workshop at the campus of the Swiss Federal Institute of Technology in Lausanne, Switzerland (EPFL) between the 2nd and the 5th of September 2024 appears to be well in line with previous workshops in 1999 (CERN), 2001 (Fermilab), 2013 (CERN) and 2018 (LBNL).
We look forward to welcome you all at EPF in Lausanne!
