轻子不对称性与宇宙种子磁场的增长

Lepton asymmetries and the growth of cosmological seed magnetic fields

V. B. Semikoz, J. W. F. Valle

摘要:

原始宇宙学超磁场在电弱相变(EWPT)之前包裹着早期宇宙等离子体。由于标准模型中存在的长程宇称违反规范相互作用,它们的大小被放大,从而开辟了一种新的微扰方式,解释了观测到的星系际磁场。

英文摘要:

Primordial cosmological hypermagnetic fields polarize the early Universe plasma prior to the electroweak phase transition (EWPT). As a result of the long range parity violating gauge interaction present in the Standard Model their magnitude gets amplified, opening a new, perturbative way, of accounting for the observed intergalactic magnetic fields.
