Cosmic neutrino flux and spin flavor oscillations in intergalactic medium

Understand

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 ($\mu_{\nu}$) owing to quantum loop corrections, this may result in spin-flavor oscillations, which can affect the cosmic neutrino flux.
