DESCRIPTION:While all models of Majorana neutrino masses lead to the same 
 dimension five effective operator\, which does not conserve lepton number\
 , the dimension six operators induced at low energies conserve lepton numb
 er and differ depending on the high energy model of new physics. We derive
  the low-energy dimension six operators which are characteristic of generi
 c Seesaw models\, in which neutrino masses result from the exchange of hea
 vy fields which may be either fermionic singlets\, fermionic triplets or s
 calar triplets. The resulting operators may lead to effects observable in 
 the near future\, if the coefficients of the dimension five and six operat
 ors are decoupled along a certain pattern\, which turns out to be common t
 o all models. The phenomenological consequences are explored as well\, inc
 luding their contributions to $\\mu \\to e \\gamma$ and new bounds on the 
 Yukawa couplings for each model.\n\nhttps://indico.ific.uv.es/event/1589/
