JUNE 2011 - Electron neutrino appearance at T2K

The T2K experiment, whose primary purpose is to study neutrino interactions at a large distance from their source, has detected 6 electron neutrino candidate events based on the data collected before March 11, 2011. For the first time, it was possible to observe an indication that muon neutrinos are able to transform into electron neutrinos over a distance of 295 km through the quantum mechanical phenomena of neutrino flavor oscillations.
The IFAE neutino group has actively contributed to the analysis in several aspects of the near detector data analysis for flux normalization and systematic cross-checks.
