A High Statistics Search for muon-neutrino(anti-muon-neutrino) ---> electron-neutrino(anti-electron-neutrino) Oscillations in the Small Mixing Angle Regime

Abstract

Limits on ${\nu }_{\mu }({\overline{\nu }}_{\mu })\to {\nu }_e({\overline{\nu }}_e)$ oscillations based on a statistical separation of ${\nu }_{e}N$ charged current interactions in the CCFR detector at Fermilab are presented. ${\nu }_e$ interactions are identified by the difference in the longitudinal shower energy deposition pattern of ${\nu }_{e}N\to eX$ versus ${\nu }_{\mu }N\to {\nu }_{\mu }X$ interactions. Neutrino energies range from 30 to 600 GeV with a mean of 140 GeV, and ${\nu }_{\mu }$ flight lengths vary from 0.9 km to 1.4 km. The lowest 90% confidence upper limit in $si{n}^{2}2\alpha$ of $1.1\times 10^{-3}$ is obtained at $\Delta m^2\sim 300e{V}^2$. For $si{n}^{2}2\alpha =1$, $\Delta m^2>1.6e{V}^2$ is excluded, and for $\Delta m^2\gg 1000e{V}^2$, $si{n}^{2}2\alpha >1.8\times 10^{-3}$ is excluded. This result is the most stringent limit to date for $\Delta m^2>25e{V}^2$ and it excludes the high $\Delta m^2$ oscillation region favoured by the LSND experiment. The ${\nu }_{\mu }$-to-${\nu }_e$ cross-section ratio was measured as a test of ${\nu }_{\mu }({\bar{\nu }}_{\mu })\leftrightarrow {\nu }_e({\bar{\nu }}_e)$ universality to be $1.026\pm 0.055$.
