DESCRIPTION:Speakers: Dr. MONDRAGON CEBALLOS\, Myriam (Instituto de Fisica
 \, UNAM)\nIn this talk we give an overview of some work on Standard Model 
 extensions\, with emphasis on the rôle of symmetries in understanding the
  masses and mixing in quarks and leptons.  In top down models\, we explain
  how the method of reduction of couplings leads to finite theories\, which
  exhibit scale invariance\, and point to underlying symmetries at the unif
 ication scale\, relating the gauge and Yukawa couplings\, thus rendering v
 ery predictive theories.  In the bottom up approach\, we follow a phenomen
 ological approach to propose possible flavor symmetries at low energies in
  multi-Higgs SM extensions\, to explain the observed mixing patterns in qu
 arks and leptons.  A possible path on how to connect both approaches is th
 en  proposed.\n\nhttps://indico.nucleares.unam.mx/event/2449/contribution/
