DESCRIPTION:Speakers: Pavlo Minaiev (Oles Honchar Dnipro National Universi
 ty)\nWe investigate the electroweak phase transition in the Standard Model
 s with accounting for the spontaneous vacuum magnetization. It is known th
 at for the mass of Higgs boson grater then 75 GeV\, the electroweak phase 
 transition is second order. But according to Sakharov's conditions for the
  formation of the baryon asymmetry of the Universe\, it should be strong f
 irst order. The spontaneously generated fields are temperature dependent a
 nd they have an influence on the phase transition.\nChromomagnetic fields 
 $B_3$ and $B_8$ have to be created spontaneously in the gluon sector of QC
 D at temperature $T > T_d$ higher the deconfinement temperature $T_d$. Usu
 al magnetic field $H$ should also be spontaneously generated because of qu
 ark-loop. For $T$ near $T_{EW}$\, this field should be present too\, so th
 ey can change the behavior of phase transition.\nThe critical temperature 
 for the electroweak phase transition is estimated in Standart model and in
  the scalar theory. The field strengths $B_3(T)$\, $B_8(T)$ and $H(T)$ at 
 relevant temperatures are also estimated.\n\nhttps://indico.bitp.kiev.ua/e
