Recent detection of the neutrino events IceCube-170922A, 13 muon-neutrino events observed in 2014-2015 and IceCube-141209A by IceCube observatory from the Blazars, namely TXS 0506+056, PKS 0502+049/TXS 0506+056 and GB6 J1040+0617 respectively in the state of enhanced gammaray emission, indicates the acceleration of cosmic rays in the blazar jets. The photo-meson (pγ) interaction cannot explain the IceCube observations of 13 neutrino events. The non-detection of broadline emission in the optical spectra of the IceCube blazars, however, question the hadronuclear (pp) interaction interpretation through relativistic jet meets with high density cloud. In this work, we investigate the proton blazar model in which the non-relativistic protons that come into existence under the charge neutrality condition of the blazar jet can offer sufficient target matter for pp interaction with shock-accelerated protons, to describe the observed high-energy gamma-rays and neutrino signal from the said blazars. Our findings suggest that the model can explain consistently the observed electromagnetic spectrum in combination with appropriate number of neutrino events from the corresponding blazars.PACS numbers: 96.50.S-, 98.70.Rz, 98.70.Sa

Violation of equivalence principle predicts that neutrinos of different flavour couple differently with gravity. Such a scenario can give rise to gravity induced flavour oscillations in addition to the usual mass flavour neutrino oscillations during the neutrino propagation.Even if the equivalence principle is indeed violated, their measure will be extremely small. We explore the possibility to probe the violation of equivalence principle (VEP) for the case of long baseline (LBL) neutrinos in a 4-flavour neutrino framework (3 active + 1 sterile) where both mass and gravity induced oscillations are considered. For the muon neutrino flux from a neutrino factory or accelerator, the muon yields are computed and compared at a far end detector with and without VEP. For the first time, we explore a possibility demonstrating that in 4-neutrino (3 active + 1 sterile) framework considering the neutrino oscillation with both VEP and matter effect, even a very small violation of equivalence principle can be probed in a long baseline neutrino experiment.
