DESCRIPTION:Abstract: With very few exceptions\, the large amount of avail
 able experimental bounds on heavy neutral leptons - HNL - have been derive
 d relying on the assumption of the existence of a single (usually Majorana
 ) sterile fermion state that mixes with only one lepton flavor. However\, 
 most of the  extensions of the Standard Model involving these new particl
 es predict the existence of several HNLs\, with complex mixing patterns to
  all flavors. Consequently\, most of the experimental bounds for HNLs need
  to be recast before being applied to a generic scenario. In this work\, w
 e focus on LHC searches of heavy neutral leptons and discuss how to reinte
 rpret the available bounds when it comes to consider mixings to all active
  flavors\, not only in the case with a single HNL\, but also in the  case
  when more heavy neutral leptons are involved. In the latter case\, we als
 o consider the possibility of interference effects and show how the bounds
  on the parameter space should be recast.\n\nhttps://indico.ific.uv.es/eve
