A subject of major importance in fundamental physics is the investigation of the origin of Electroweak Symmetry Breaking. The mechanism of mass generation through the spontaneous breaking of a gauge symmetry is called the Brout-Englert-Higgs mechanism and is associated with the appearance of a physical scalar boson.

The discovery announced at CERN on 4th July 2012 by the ATLAS and CMS Collaborations of a boson at a mass close to 125 GeV/c2, compatible with this scalar boson of the Standard Model, the so-called Higgs boson, mainly in yy, ZZ and WW decay modes, with compatible evidence also found at Fermilab in the bb mode, changed the landscape. This important discovery was acknowledged as decisive for the attribution of the 2013  Nobel Prize in Physics awarded jointly to François Englert and Peter Higgs.

This 11th workshop of the « Higgs Hunting » series organized in Orsay and
Paris on September 20-22, 2021 will discuss the developments of LHC Run-2
analyses, detailed studies of the new boson and possible deviations from
Standard Model properties. Searches for additional bosons, future prospects
for Run-3 and beyond , and recent theoretical developments will also be covered.

Some possibilities are available to help young participants with a grant covering the fee. This support is stricly based on actual need. For instance, we typically expect large collaborations to support their speakers. Candidates are invited to contact Valérie Brouillard (brouilla@lal.in2p3.fr)

Because of COVID-19, there are uncertainties on the format of Higgs Hunting 2021 . We do not know yet if it will be [full zoom] or  [ face-to-face and zoom]. It will be decided soon and announced. Please pre register and you will not have to pay the fees. You will receive the green light to to it later.

Registration deadline: September 8th, 2021

Martinus Veltman, whose work on renormalization of Yang–Mills theory with his former student Gerardus ‘t Hooft is one of the major achievements of twentieth century high energy physics, passed away on January 4th.

The Higgs Hunting workshop expresses its deepest condolences to his family.
