论文摘要

中微子的快速成对转化可能会影响中微子致密来源核心的风味分布。我们探索了一个简化的框架内的碰撞与快速转化之间的相互作用,该框架假定没有空间不均匀性的中微子气体中与角度无关,方向变化的碰撞。对抗期望,我们发现碰撞可能会增强快速的风味转化,而不是抑制它们。我们的工作强调了需要自愿考虑中微子角分布的冲突的反馈,以便在快速成对转换的背景下预测风味结果。

Fast pairwise conversions of neutrinos may affect the flavor distribution in the core of neutrino-dense sources. We explore the interplay between collisions and fast conversions within a simplified framework that assumes angle-independent, direction-changing collisions in a neutrino gas that has no spatial inhomogeneity. Counter to expectations, we find that collisions may enhance fast flavor conversions instead of damping them. Our work highlights the need to take into account the feedback of collisions on the neutrino angular distributions self-consistently, in order to predict the flavor outcome in the context of fast pairwise conversions reliably.
