Bounds on Relic Neutrino Masses in the Z-burst Model
Neutrinos from far-away sources annihilating at the Z resonance on relic neutrinos may give origin to the extreme-energy cosmic rays (EECR). If “Z-bursts” are responsible for the EECR events, then we show that the non-observation of cosmic ray events at energies above 2 ×1020 eV by the AGASA Collaboration implies a lower bound ∼ 0.3 eV on the relic neutrino mass. Since this mass exceeds the mas...
متن کاملNeutrino clustering and the Z-burst model
The possibility that the observed Ultra High Energy Cosmic Rays are generated by high energy neutrinos creating “Z-bursts” in resonant interactions with the background neutrinos has been proposed, but there are difficulties in generating enough events with reasonable incident neutrino fluxes. We point out that this difficulty is overcome if the background neutrinos have coalesced into “neutrino...
متن کاملBounds on the Masses and Couplings of Leptoquarks from Leptonic Partial Widths of the Z
The vertex corrections to the leptonic partial widths of the Z induced by leptoquarks that couple leptons to the top quark are considered. We obtain stringent bounds on the parameter space of the masses and Yukawa couplings of these leptoquarks, using the latest information on the Z → ll decay widths measured at LEP. Leptoquarks coupling with electroweak strength to top quarks are constrained t...
