Sphaleron碎片中的磁螺旋度
Magnetic Helicity in Sphaleron Debris
摘要:
我们开发了一种分析技术来评估从sphaleron衰变碎片的磁螺旋度。我们发现,重子数的产生导致左手磁场,并在后期的磁螺旋度是守恒的。我们的分析明确地表明了闪锌矿介导的宇宙重子生成和宇宙磁生之间的联系。
英文摘要:
We develop an analytical technique to evaluate the magnetic helicity in the debris from sphaleron decay. We show that baryon number production leads to left-handed magnetic fields, and that the magnetic helicity is conserved at late times. Our analysis explicitly demonstrates the connection between sphaleron-mediated cosmic baryogenesis and cosmic magnetogenesis.
