Update on Atmospheric Neutrinos

María Concepción González García

(I.F.I.C., Valencia)

I will review the subject of the atmospheric neutrino anomaly. I will discuss the impact of recent experimental results on the determination of atmospheric neutrino oscillation parameters using all published results on atmospheric neutrinos, including the new large statistics data of Super-Kamiokande. I will show the results from this reanalysis in terms of both $\nu_\mu \to \nu_\tau$ and $\nu_\mu \to \nu_e$ channels using new improved calculations of the atmospheric neutrino flux. I will compare the sensitivity attained in atmospheric neutrino experiments with those of accelerator and reactor neutrino oscillation searches, including the recent Chooz experiment. I will also briefly comment on the implications of atmospheric neutrino data in relation to future searches for neutrino oscillations with long baselines, such as the K2K, MINOS, ICARUS and NOE.

The almuerzo-seminario is intended to be an informal seminar and an open forum for discussion.

You are wellcome to bring your own bocata (sandwich), or coffee or tea.
