Exploring Electric Dipole Moments of Heavy Flavors
Joan Ruiz (IFIC, Valencia U. - CSIC)

Recent experimental results on the B-anomalies, CP-violation in charm, or the muon (g-2) hint at new physics models where the additional interactions are specific to the quark and lepton families. In this context, searches for the electric dipole moment (EDM) of heavy-flavored baryons are especially motivated. Using bent crystal technology and the highly energetic beams of the LHC, the EDM of very short-lived particles can be measured for the first time (1612.06769, 2010.11902, 2110.00845). In addition, the direct determination of the tau (g-2) is possible with this novel experimental method (1901.04003). The different aspects of the measurement will be summarized along with the expected sensitivities. From a more phenomenological perspective, we will also see what are the effective operators contributing to the baryon EDM and what is their expected size. In particular, new limits on the charm and bottom quark EDM are derived from already existing measurements (1905.02513). We will analyze the implications of these bounds for new physics models, comparing them against other competing observables.
