Higgs (N)NLO MC and Tools Workshop for LHC RUN-2

17 Dec 2014, 09:00 → 19 Dec 2014, 17:00 Europe/Zurich

222/R-001 (CERN)

Bruce Mellado Garcia (University of the Witwatersrand), Daniela Rebuzzi (Pavia University), Junichi Tanaka (University of Tokyo), Markus Schumacher (Albert-Ludwigs-Universität Freiburg), Michael Duehrssen-Debling (CERN), Nikolaos Rompotis (University of Washington), Reisaburo Tanaka (LAL-Orsay)

This workshop is intended to follow up the recent progresses in (N)NLO MCs and Tools in Higgs physics to prepare for LHC RUN-2 at 13/14TeV which will start in spring 2015. After reviewing the lessons from RUN-1, 1) recent theoretical progresses in (N)NLO MCs and Tools and 2) MC validation status and wish lists by the experimental collaborations will be discussed, followed by the round table discussions.
