Description

The Strong CP problem has long been one of the most compelling windows into physics beyond the Standard Model. In light of recent, partially conflicting, works about the topic, we organize a Rapid Response online Workshop targeting the broad European Astroparticle Theory comunity through EuCAPT. The event will host members of three different groups delivering short talks, followed by a panel discussion.

Everyone is welcome! The event will be streamed over zoom. 
Before and during the event, everyone is encouraged to post and vote on questions and comments on the Slido page for the event.

Confirmed speakers: 

  • Bjorn Garbrecht [Technische Universität München]
  • Joshua N. Benabou [Theoretical Physics Group, Lawrence Berkeley National Laboratory, Berkeley]
  • David E. Kaplan [Department of Physics & Astronomy, The Johns Hopkins University]

Discussion session moderated by

  • Tim Cohen [CERN]

Confirmed panel members:

  • Raffaele Tito D'Agnolo
  • Massimo D'Elia 
  • Nick Dorey
  • Edward Witten
