DESCRIPTION:Speakers: Cristian Felipe Sierra Fonseca\n\nThe origin of the 
 observed baryon asymmetry of the Universe (BAU) is one of the deepest puzz
 les in particle physics and cosmology. We demonstrate for the first time t
 hat new physics explaining the long standing charged $B$ meson anomalies\,
  $R(D^{(*)})$\,  can be the source of CP violation that explains the obse
 rved BAU. We consider the general two Higgs doublet model with complex Yuk
 awa couplings and compute the BAU in the semiclassical formalism. After im
 posing constraints from both flavour observables and the electron electric
  dipole moment (eEDM)\, we find that a significant BAU can still be genera
 ted for a variety of benchmark points in the parameter space\, assuming th
 e occurrence of a sufficiently strong first order electroweak phase transi
 tion. These scenarios\, which explain both $R(D^{(*)})$ and the BAU\, can 
 be probed  with future eEDM experiments and Higgs factories measurements.
