Higgs Couplings 2016

9 Nov 2016, 08:00 → 12 Nov 2016, 12:20 America/Los_Angeles

Kavli Auditorium (SLAC)

Giacinto Piacquadio (SLAC National Accelerator Laboratory (US)), Stefan Hoeche (SLAC), maria herraez (SLAC National Laboratory)

Higgs Couplings 2016 is this year's installment of an annual workshop devoted to new experimental and theoretical results on the Higgs boson. The 2016 workshop will present the latest results from the LHC run 2 on the Higgs boson mass, spin/parity, and couplings and will present new theoretical work devoted to the measurement of Higgs parameters and possibilities for exotic Higgs decays. The workshop will provide an opportunity for critical discussion of the current strategies for studying the Higgs boson at the LHC and the next steps in the LHC program.

Higgs Couplings 2016 will include several sessions of parallel contributions on current research topics.   The organizers encourage the submission of abstracts for 15-minute talks.  In selecting the talks to be presented, we will give priority to graduate students and postdoctoral fellows.

The workshop will be preceded by a Meeting on Exotic Higgs Decays

Previous editions of Higgs Couplings were held at

• Lumley Castle, 2015
• Torino, 2014
• Freiburg, 2013
• Tokyo, 2012
