DESCRIPTION:Speakers: Sergey Godunov (LPI)\nWe study the process $e^+e^- \
 \to W^+W^-$ in case of seesaw type-I with two implementations of heavy-lig
 ht neutrino mixing: a linearized mixing approximation applied in popular m
 odels and an exact unitary mixing scheme. We conclude that the approximate
  realization leads to physically incorrect results for this process\, whil
 e exact unitary mixing provides some signatures that can be experimentally
  checked at future $e^+e^-$-colliders.\n\nhttps://indico.particle.mephi.ru
