论文摘要
在外部磁场中，电动Sphaleron的能量代表了Baryon和Lepton数量违规的能量屏障 - - - 降低但仍不为零，直到Higgs质量和电荷设置的上部Ambjorn-Operen临界场强度为止。我们通过在存在外部磁场的情况下，在整个场强度范围内，直到能量屏障消失，我们通过数值计算SPHALERON构型来证明这一点。我们讨论了早期宇宙中男性生成的影响，以及观察到重型离子碰撞中巴属和轻子数量违反的可能性。
In an external magnetic field, the energy of the electroweak sphaleron---representing the energy barrier to baryon and lepton number violation---decreases but remains nonzero until the upper Ambjorn-Olesen critical field strength set by the Higgs mass and the electric charge, where it vanishes. We demonstrate this by numerically computing the sphaleron configuration in the presence of an external magnetic field, over the full range of field strengths until the energy barrier vanishes. We discuss the implications for baryogenesis in the early universe, and the possibility of observing of baryon and lepton number violation in heavy-ion collisions.
