TL;DR
This paper proposes that the PeV energy neutrino events observed by IceCube can be explained by resonance production of color octet neutrinos with masses between 500 and 800 GeV, offering a novel interpretation of the data.
Contribution
It introduces a new interpretation of IceCube PeV neutrino events as resonance production of color octet neutrinos, expanding beyond existing explanations.
Findings
PeV neutrino events can be explained by color octet neutrino resonance.
Color octet neutrinos with masses 500-800 GeV fit the observed data.
Supports the viability of color octet neutrinos as an astrophysical phenomenon.
Abstract
IceCube collaboration has published two papers on ultrahigh energy neutrinos observation, recently. They have used the data collected in two years in their first publication, which reveals observation of two PeV energy neutrino events. The second publication of the collaboration including more data has also confirmed main features of the former paper. In literature, various interpretations of the IceCube data have been proposed. In this study, it is shown that PeV energy neutrino events observed by the IceCube collaboration can be interpreted as resonance production of color octet neutrinos with masses in GeV range.
