Search for νμ→νe oscillations with the OPERA experiment in the CNGS beam

The OPERA hybrid detector, designed to prove neutrino oscillations in the νμ→ντ channel, was exposed to the CNGS νμ beam at a distance of 730 km from the neutrino source. Profiting of the tracking capabilities of its Emulsion Cloud Chamber system, OPERA can perform also a search for νμ→νe oscillations. Current results are compatible with the non-oscillation hypothesis in the three flavour mixing model. The same data allow to constrain the...
