ATLAS-CMS Monte Carlo Generators Workshop

11 Jan 2016, 08:30 → 12 Jan 2016, 18:15 Europe/Zurich

222/R-001 (CERN)

James William Monk (Niels Bohr Institute, University of Copenhagen), Josh Bendavid (California Institute of Technology (US)), Marjorie Shapiro (Lawrence Berkeley National Lab. (US)), Michelangelo Mangano (CERN), Monica D'Onofrio (University of Liverpool (GB)), Pietro Govoni (Universita & INFN, Milano-Bicocca (IT)), Roberto Covarelli (University/INFN Torino (IT))

Workshop focused on the discussion of the status, issues, needs and prospects for further development of the MC generators for LHC physics. The meeting will be driven by introductory dedicated talks, both theoretical and exeprimental, followed by ample time for discussion.

​VIDYO connection will be available.
