Higgs Hunting 2026

16 sept. 2026, 09:00 → 18 sept. 2026, 19:00 Europe/Paris

IJCLab Orsay / APC Paris

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 16th workshop of the « Higgs Hunting » series organized on September 16-18, 2026 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 new results from 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.
