中微子自旋进动引起的UHE中微子通量的减少

A reduction in the UHE neutrino flux due to neutrino spin precession

J. Barranco, O. G. Miranda, C. A. Moura, A. Parada

摘要:

基于对来自伽马射线暴或活动星系核的UHE中微子的严格的通量限制,我们探讨了在这种天体中产生的活动中微子由于中微子磁矩mu_nu而振荡到无菌右手态的可能性.我们发现,一个小到μ_nu ~ 1 E-15 μ_B的值可以产生这样的转变,由于强烈的磁场,预计在这些对象。

英文摘要:

Motivated by the stringent flux limits for UHE neutrinos coming from gamma ray burst or active galactic nuclei, we explore the possibility that the active neutrinos generated in such astrophysical objects could oscillate to sterile right handed states due to a neutrino magnetic moment mu_nu. We find that a value as small as mu_nu ~1E-15 mu_B could produce such a transition thanks to the intense magnetic fields that are expected in these objects.
