DESCRIPTION:We argue that the magnetic helicity conservation is violated a
 t the lepton stage in the evolution of early universe due to the parity vi
 olation in SM of electroweak interactions. As a result a cosmological magn
 etic field which can be a seed for the galactic dynamo obtains from the be
 ginning a substantial magnetic helicity which has to be taken into account
  in the magnetic helicity balance at the later stage of galactic dynamo. T
 he particle physics mechanism suggested in our works depends neither on he
 licity of matter turbulence with plasma vortices resulting in the standard
  $\\alpha$ - effect in dynamo theory nor on general rotation. The mechanis
 m can result in a self-exitation of an (almost) uniform cosmological magne
 tic field.\n\nhttps://indico.ific.uv.es/event/1458/
