Dnia 27 marca (piątek) o godzinie 11:30, w sali B2.38 odbędzie się seminarium, na którym zostanie wygłoszony referat pt.:
„Fermat primes in flavour mixing and mass hierarchies”
Referuje: prof. dr hab. Jacek Ciborowski (IFD UW)
A Balmer-like empirical analysis of quark and neutrino mixing angles and of the charged-lepton mass hierarchy suggests a remarkable interplay between number theory and geometry, involving Fermat primes 5 and 17 (or equivalently the golden ratio in place of the former). The resulting pattern fixes two of the three a priori unknown parameters entering the (presently frequently exploited) Froggatt–Nielsen description of flavour hierarchies. This may provide useful guidance for further phenomenological studies (quark and neutrino masses) and possibly for the search for a more fundamental theory of flavour.
