DESCRIPTION:Speakers: DE MEDEIROS VARZIELAS\, Ivo (Instituto Superior Tecn
 ico)\nWe show that a universal texture zero in the (1\,1) position of all 
 fermionic mass matrices\, including heavy right-handed Majorana neutrinos 
 driving a type-I see-saw mechanism\, can lead to a viable spectrum of mass
 \, mixing and CP violation for both quarks and leptons\, including (but no
 t limited to) three important postdictions:  the Cabibbo angle\, the charg
 ed lepton masses\, and the leptonic `reactor' angle. We model this texture
  zero with a non-Abelian discrete family symmetry that can easily be embed
 ded in a grand unified framework\, and discuss the details of the phenomen
 ology after electroweak and family symmetry breaking. We provide an explic
 it numerical fit to the available data and obtain excellent agreement with
  the 18 observables in the charged fermion and neutrino sectors with just 
 9 free parameters.  We further show that the vacua of our new scalar famil
 on fields are readily aligned along desired directions in family space\, a
 nd also demonstrate discrete gauge anomaly freedom at the relevant scale o
 f our effective theory.\n\nhttp://indico.fuw.edu.pl/contributionDisplay.py
