Higgs 2021 is this year's installment of an annual conference devoted to new experimental and theoretical results on the Higgs boson. The 2021 conference will present the latest results from the LHC 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 conference will provide an opportunity for critical discussion of the current strategies for studying the Higgs boson at the LHC and the next steps beyond the LHC. Higgs 2021 will include several sessions of parallel and plenary contributions on current research topics.

Update Sep 9th: 

The in-person component of the Higgs 2021 conference has been cancelled. The conference will be held virtually. This decision is driven not only by US-wide travel restrictions (from other countries), but also by self-imposed travel restrictions by DOE, DOE labs and several US institutions which make it impossible also for most US-based participants and speakers to travel to Stony Brook.

If you have any questions, you can reach the conference administrators at higgs2021-admins@cern.ch, and the full local organizing committee at higgs-couplings-Higgs2021-LOC@cern.ch. If you have any questions related to the program, please also add the program committee in cc: higgs-couplings-Higgs2021-PC@cern.ch.
