3rd workshop on electromagnetic dipole moments of unstable particles

11 déc. 2023, 08:50 → 12 déc. 2023, 18:20 Europe/Paris

100/-1-A900 - Auditorium Joliot Curie (IJCLab)

The scope of the workshop is to stimulate a constructive scientific discussion on electromagnetic dipole measurements of unstable particles proposed for the LHC. In particular for charm and strange baryons and tau leptons.  The theoretical, experimental and machine aspects of the proposal will be reviewed and critically discussed in preparation of a future experiment at the CERN LHC. The meeting will touch few main topics:

• electric and magnetic dipole moments of baryons and leptons;
• channeling and spin precession in bent crystals;
• a new fixed-target experiment at the LHC with bent crystals;
• spin precession in the LHCb magnet;
• experimental techniques for reconstruction of long-lived particles.
