Cosmic neutrino flux and spin flavor oscillations in intergalactic medium
arXiv:2207.13034 · doi:10.1016/j.physletb.2023.137791
Abstract
The ultra high energy (UHE) cosmic neutrinos are expected to play a pivotal role in the disquisition of physics beyond the standard model of particle physics as well as serve as an ideal cosmic messengers. This epitomizes the selling point of several currently running or planned neutrino telescopes. The UHE cosmic neutrinos usually perambulate gargantuan scales in the extragalactic universe having a magnetic field. If neutrinos have a finite magnetic moment () owing to quantum loop corrections, this may result in spin-flavor oscillations, which can affect the cosmic neutrino flux. Using the current limit and assuming neutrinos to be Dirac particles, we show that the flux of cosmic neutrinos will reduce by half if they traverse few Mpcs through the intergalactic magnetic field, in the range of to . Moreover, one can safely neglect the effect of if the current upper bound is improved by a few orders of magnitude even if the neutrinos travel through the size of the visible universe.
