SUMMARY:Fermion masses and mixings in F-theory GUTs\, Theory Seminar (
 High Energy/Cosmology)\, Gianluca Zoccarato\, Instituto de Fisica Teor
 ica\, Madrid
DESCRIPTION:In this talk I will discuss the structure of Yukawa coupli
 ngs in local SU(5) F-theory models with E7 and E8 enhancement. In thes
 e 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 i
 nto account non-perturbative effects the other two families acquire a 
 mass which is hierarchically smaller compared to the mass of the first
  generation. <br>
\nI will show that there is a unique model embeddabl
 e both in E7 and in E8 with a good hierarchical structure for the ferm
 ion masses. Finally I will discuss the structure of the CKM matrix for
  this particular model.
