| 14:00 - 15:00 Weekly Seminar HEPCo Group On the Tau flavor of the cosmic neutrino flux School PHYSICS Observation of high energy cosmic neutrinos by ICECUBE has ushered in a new era in exploring both cosmos and new physics beyond the Standard Model (SM). In the standard picture, although mostly $nu_mu$ and $nu_e$ are produced in the source, oscillation will produce $nu_tau;en; route$. Certain beyond SM scenarios, like interaction with ultralight DM can alter this picture. Thus, the flavor composition of the cosmic neutrino flux can open up the possibility of exploring certain beyond the SM scenarios that are inaccessible otherwise. We show that the $tau$ flavor holds a special place among the neutrino flavors in elucid ... |
