Multi partonic interactions at LHC

14 Oct 2012, 08:00 → 17 Oct 2012, 18:30 Israel

Melamed hall (Tel Aviv University)

Aharon Levy (Tel Aviv University), Halina Abramowicz (Tel Aviv University (IL))

Workshop with limited number of participants devoted to the problems of multiparton interactions at the collider energies. The workshop will combine talks and discussions with the aim to single out outstanding problems and outline directions of the future studies. The workshop is sponsored by the Israel Science Foundation and Tel Aviv University
