Physics at the High-Luminosity LHC

11 May 2015, 08:30 → 13 May 2015, 18:00 Europe/Zurich

4/3-006 - TH Conference Room (CERN)

Aleandro Nisati (Universita e INFN, Roma I (IT)), Andreas Weiler (CERN), Gavin Salam (CERN), Markus Klute (Massachusetts Inst. of Technology (US)), Michelangelo Mangano (CERN), Vincenzo Vagnoni (Universita e INFN, Bologna (IT))

Workshop dedicated to the proton-proton physics programme of the High-Luminosity phase of the LHC. The meeting will be driven by dedicated talks, followed by ample time for discussion. It will provide a dedicated open forum, to continue and expand the work initiated during the Aix-les-Bains ECFA 2013 and 2014 HL-LHC workshops.

We envisage 4 main discussion topics:

• Higgs physics
• BSM searches
• SM precision opportunities and needs
• Flavour

VIDYO connection will be available.
