弥散超新星中微子背景的下降

Dips in the Diffuse Supernova Neutrino Background

Yasaman Farzan, Sergio Palomares-Ruiz

摘要:

标量(费米子)暗物质的质量在兆电子伏范围内耦合到普通中微子和另一个费米子(标量)的动机是建立辐射产生的中微子质量和暗物质遗迹密度之间的联系。有了这样的耦合,宇宙超新星中微子在向我们飞来的途中,可能会与背景暗物质粒子发生共振相互作用,从而导致它们的红移积分光谱下降。目前和未来的中微子探测器,如Super-Kamiokande,LENA和Hyper-Kamiokande,可能能够探测到这种扭曲。

英文摘要:

Scalar (fermion) dark matter with mass in the MeV range coupled to ordinary neutrinos and another fermion (scalar) is motivated by scenarios that establish a link between radiatively generated neutrino masses and the dark matter relic density. With such a coupling, cosmic supernova neutrinos, on their way to us, could resonantly interact with the background dark matter particles, giving rise to a dip in their redshift-integrated spectra. Current and future neutrino detectors, such as Super-Kamiokande, LENA and Hyper-Kamiokande, could be able to detect this distortion.
