DESCRIPTION:\n    We will analize the relevance of the 1-loop corrections 
 when extracting bounds on non-unitarity in the context of low scale seesaw
 s with an approximate B?L symmetry. These models are characterized by elec
 troweak scale Majorana masses and large Yukawas. Previous results in the l
 iterature showed that a partial cancellation between these important loop 
 corrections and the tree level contributions could relax some constraints.
  However\, we will show that this cancellation can only take place in pres
 ence of large violations of the B?L symmetry\, that lead to unacceptably l
 arge contributions to the light neutrino masses at loop level. The impact 
 of the 1-loop corrections in the neutrinoless double beta decay phenomenol
 ogy will also be discussed.\n\nhttps://indico.ific.uv.es/event/2697/
