Improved search for ${\nu }_{\mu }\to {\nu }_e$ oscillation in a long-baseline accelerator experiment

K2K collaboration, S. Yamamoto

We performed an improved search for ${\nu }_{\mu }\to {\nu }_e$ oscillation with the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment, using the full data sample of $9.2 \times…
