Theory Seminar (High Energy/Cosmology)
Fermion masses and mixings in F-theory GUTs
Date: Friday, April 8th
Time: 2:00 pm
Place: 5280 Chamberlin Hall
Speaker: Gianluca Zoccarato, Instituto de Fisica Teorica, Madrid
Abstract: In this talk I will discuss the structure of Yukawa couplings in local SU(5) F-theory models with E7 and E8 enhancement. In these models the whole flavour structure for the MSSM charged fermions is encoded in a small region of the entire compactification space. While only one generation of quarks and leptons acquires mass after taking into account non-perturbative effects the other two families acquire a mass which is hierarchically smaller compared to the mass of the first generation.
I will show that there is a unique model embeddable both in E7 and in E8 with a good hierarchical structure for the fermion masses. Finally I will discuss the structure of the CKM matrix for this particular model.
