Description

The origin of Electroweak symmetry breaking is one of the central topics of research in fundamental physics. The discovery of a Higgs boson at CERN on July 4th, 2012, following a hunt that spanned several decades and multiple colliders, changed the landscape of these investigations and provided key evidence for the Brout-Englert-Higgs mechanism of mass generation through the spontaneous breaking of Electroweak symmetry.

More than ten years later, the hunt goes on several fronts, in particular for:

  • New physics through precision studies of the properties of the Higgs boson : in particular its mass, spin and couplings to other Standard Model particles.
  • New production and decay modes, in particular in processes involving multiple Higgs bosons which provide key insight into the shape of the Higgs potential.
  • New Higgs-like states and signals for physics beyond the Standard Model.

The 14th workshop of the « Higgs Hunting » series organized on September 23-25 2024 will present an overview of these topics, focusing in particular on new developments in the LHC Run-2 analyses, detailed studies of Higgs boson properties and possible deviations from Standard Model predictions. Highlights will also include a first look at LHC Run-3 analyses, prospects from studies at future colliders, and recent theoretical developments.

The workshop will be held in person in Orsay, for the first day, and Paris, for the two following days, to continue the Higgs Hunting tradition of lively discussions during and after the sessions. Remote participation will also be made possible for those unable to attend in person. No registration fees are asked for remote participation.

Peter Higgs passed away on April 8th 2024. In the 1960s, Peter Higgs, and others, proposed that spontaneous symmetry breaking could provide masses for the mediators of the weak interactions, the W and Z bosons. One major prediction of this idea is the existence of a new particle, now called the Higgs boson, which was finally discovered at CERN in 2012. We now know that the Higgs field is most probably at the origin of the masses of all elementary particles. The three papers written by Peter Higgs between 1964 and 1966 are part of the foundations of the Standard Model and among the most influential ones in particle physics and beyond.

The Higgs Hunting workshop, which owes its name to Peter Higgs, expresses its deepest condolences to his family.
