Title: Flow of hypermagnetic helicity in the embryo of a new phase in the electroweak phase transition

Title: 新相变阶段胚胎中的超磁螺旋流

Authors:P.M. Akhmet'ev, V.B. Semikoz, D.D. Sokoloff
Abstract: The dynamics of the magnetic helicity during the electroweak phase transition in the early Universe is studied. It is shown that the boundary surface between symmetric (hypermagnetic) phase and Maxwellian phase with a broken symmetry is a membrana for the separation of the magnetic helicity. Assuming the total linking number of knots of hypermagnetic field is negative, it is proved that the helicity rising in the Maxwellian phase is left-handed.
Abstract: 在早期宇宙中电弱相变期间磁螺旋度的动力学被研究。 表明对称(超磁)相与具有对称性破缺的麦克斯韦相之间的边界表面是磁螺旋度分离的膜。 假设超磁场结的总链接数为负,证明麦克斯韦相中出现的螺旋度是左旋的。
