The Ninth Annual Large Hadron Collider Physics (LHCP2021) conference is planned in Paris online from 7th to 12th June 2021

NEWS (12/06/201): the winners of the poster awards and the site selected to host LHCP 2023 have been announced in the closing plenary session

NEWS (28/04/2021): the second bulletin is now available on the conference website (click here)

NEWS (23/04/2021): poster abstracts have been reviewed and acceptance notifications have been sent by e-mail. Information about the poster and poster session formats are available here. More detailed instructions will be sent to the poster presenters by e-mail.

NEWS (22/04/2021): thanks to CERN and IUPAP sponsorships, no fees are required to participate to the LHCP2021 conference. Participants attending the online conference are required to register in order to receive by e-mail the instructions for the video connections.

    The LHCP conference series started in 2013 after a successful fusion of two international conferences, "Physics at Large Hadron Collider Conference" and "Hadron Collider Physics Symposium". The conference programme will be devoted to a detailed review of the latest experimental and theoretical results on collider physics, and recent results of the LHC Run II, and discussions on further research directions within the high energy particle physics community including both theory and experiment sides. The main goal of the conference is to provide intense and lively discussions between experimentalists and theorists in research areas such as the Standard Model Physics and Beyond, the Higgs Boson, Supersymmetry, Heavy Quark Physics and Heavy Ion Physics as well as the recent progress in the high luminosity upgrades of the LHC and future colliders developments.

With great regret we have concluded that the 9th LHCP conference, to be held 7-12 June 2021, will need to be fully online, due to the Covid-19 pandemic and its uncertainties.

The conference will be maintained for the same days, with an adjusted timetable to improve remote participation from around the world, similar to that of the 2020 edition of LHCP.
