Description

Conferecne poster HDThe 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 15th workshop of the « Higgs Hunting » series organized on July 15-17 2025 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.

 

Mary K. GaillardMary K. Gaillard passed away on 23 May 2025. A major figure in particle theory, she made fundamental contributions to the establishment of the Standard Model. Notably, she achieved a successful determination of the charm quark mass from kaon decays; predicted three-jet events in e+ e- collisions, providing crucial evidence for the existence of gluons; and forecasted the bottom quark mass within the framework of unified theories. She also pioneered systematic studies of Higgs boson production and decay at particle colliders, sketching its first phenomenological profile that launched its experimental hunt. Beyond the Standard Model, Mary K. made numerous and invaluable contributions to Grand Unified Theories and supersymmetric theories, including work on proton decay, supersymmetry breaking, and effective supergravity theories derived from superstrings. The Higgs Hunting workshop was honored to welcome her in 2016 as the speaker for its traditional historical talk

Mary K. spent a substantial portion of her career in France and at CERN, from her doctoral studies in Orsay to the creation of the theoretical physics laboratory LAPTh in Annecy. The Higgs Hunting workshop extends its deepest condolences to her colleagues at the University of California, Berkeley, and to her family.
