2nd CMS Higgs-charm Workshop

22 Jun 2026, 10:00 → 24 Jun 2026, 19:45 Europe/Athens

Auditorium: A. Argyriadis (National and Kapodistrian University of Athens)

Sebastian Wuchterl (CERN), Konstantinos Vellidis (National and Kapodistrian University of Athens (GR)), Jan van der Linden (Ghent University (BE)), Loukas Gouskos (Brown University (US)), Huilin Qu (CERN), Andrzej Novak (Massachusetts Inst. of Technology (US)), Javier Mauricio Duarte (Univ. of California San Diego (US))

A second workshop to bring together the different efforts in CMS and at the LHC to probe and constrain the Higgs/charm coupling. The workshop will cover existing results, ongoing analyses and future plans. An open-session is envisioned with guests from ATLAS as well as theorists.

Sessions covered will include

• Direct Searches
• Indirect Searches
• Related Efforts 
• Identification Methods
• Future Plans
  
  

The workshop will take place in Athens 22-24 June.
