Meeting the challenges of relic neutrinos

Abstract

Inspired by Gounaris-Sakurai and Lee-Zumino, we postulate that the weak vector and axial vector currents are dominated by = 1 −− and 1 ++ resonances respectively in the appropriate channels of + ¯ annihilation into quark-antiquark pairs when an ultrahigh incoming ( ¯ ) strikes a relic ¯ ( ). Despite this and some other ideas, it appears detection of relic neutrinos of just the Standard Model (SM) interactions seems extremely difficult at existing or somewhat larger neutrino telescopes. Thus any positive signal would be due to some non-standard interactions of neutrinos.
