致密天体中轴子和中微子的光生

Photo-production of axions and neutrinos in compact objects

Miguel Vanvlasselaer

AI总结:

本文详细研究了致密恒星天体中轴子和中微子的光生过程,指出其源于异常诱导的Wess-Zumino-Witten项,并通过数据驱动方法估算冷却率,最终得出该冷却通道相对于主要通道为次要的结论。

摘要:

超新星和中子星等致密恒星天体通过从其极高密度的内部发射中微子和轴子等轻粒子来进行冷却。在本文中,我们详细研究了轴子和中微子的光生。我们指出,该通道是异常诱导的 Wess-Zumino-Witten 项存在的必然结果,并计算了相关的冷却率。随后,我们进行了一项互补的数据驱动研究,其中光生率可以通过低能 $\pi$ 介子光生数据进行估算。然而我们得出结论,由轴子和中微子光生引起的冷却率相较于通常包含的主要通道通常是次要的。

英文摘要:

Compact stellar objects like supernovae and neutron stars cool by the emission of light particles like neutrinos and axions from their very dense interiors. In this article, we study in detail the photo-production of axions and neutrinos. We point out that this channel is an unavoidable consequence of the existence of the anomaly-induced Wess-Zumino-Witten term and compute the relevant cooling rates. We then perform a complementary data-driven study where the rate of photo-production can be estimated from low-energy pion photo-production data. We however conclude that the cooling rates induced by the photo-production of axions and neutrinos are typically sub-dominant with respect to the main channels usually included.
