Particle Theory Seminars

The particle theory seminars are organized by the Theory Group of the Laboratory for Particle Physics (LTP) at PSI.

The next seminar takes place on Thursday 14.12.2023 at 11:45 in WHGA/001

Update (11.12.2023): unfortunately, this seminar had to be cancelled - we are currently trying to reschedule it.

Speaker:  Jordy de Vries (University of Amsterdam & Nikhef)

Title: Electric dipole moments and the strong CP problem


Electric dipole moments (EDMs) provide stringent tests of so far undiscovered sources of CP violation. Within the Standard Model itself measurements on neutrons, atoms, and nowadays even molecules strongly constrain a possible source of CP violation within the strong interactions. There is no clear reason why nature abhors strong CP violation and this puzzle is called the Strong CP problem. But is it really a problem? If so, how can it be resolved? And can we test these resolutions? I will try to answer these question in this talk!
