Neutrino signatures in IceCube (I will be talking about Standard Model physics) Ranjan Laha

What are the neutrino signatures in IceCube? ν τ + N → τ � + N 0 ν e + N → e � + N 0 ν µ + N → µ � + N 0 and the corresponding and the corresponding and the corresponding interaction by interaction by interaction by ν µ ν e ν τ + neutral current (an exception will be discussed Learned and Pakvasa later) Astropart.Phys. 3 (1995) 267-274 interactions track double bang cascade IceCube IceCube collaboration collaboration Learned and Pakvasa Astropart. Phys. 3, 267 (1995) (upgoing) Double cascade Isolated energy deposition (cascade) / double bang Factor of ~2 energy with no track / double pulse resolution 15% deposited energy resolution resolvable above < 1 0 angular resolution O(100) TeV 10 0 angular resolution (above 100 TeV) deposited energy Ranjan Laha
