Top physics: from charge asymmetry to the boosted regime

2 May 2012, 11:00 → 4 May 2012, 18:00 Europe/Zurich

TH Theory Conference Room (CERN)

Fabrizio Margaroli (Roma "La Sapienza"), Gavin Salam (CERN, Princeton University, LPTHE (Paris)), Gilad Perez (CERN & Weizmann), Michelangelo Mangano (CERN)

Workshop on the theoretical aspects of the forward backward asymmetry (A_FB) and of the description and use of boosted tops. For A_FB, the main goal is an assessment of the theoretical uncertainty within the SM, and a discussion of possible observables, both at the tevatron and the LHC, which could provide an independent probe of the standard model (SM) or beyond the SM nature of the asymmetry observed at the tevatron. The discussion on boosted tops will be primarily focused on the theoretical issues of using boosted tops to probe top production dynamics and t-tbar spectra. EVO connection will be available: the link will appear on the agenda page 30' before the start of the meeting
