Limits on Electron-Neutrino Oscillations from the GALLEX ${}^{51}$Cr Source Experiment

Abstract

The recent result from the chromium source experiment carried out by the GALLEX collaboration implies interesting limits on the parameters $\Delta m^2$ and ${\sin }^{2}2\theta$ describing neutrino oscillations. Values of $\Delta m^2>0.17$ eV${}^2$ for maximal mixing and of ${\sin }^{2}2\theta >0.38$ for $\Delta m^2>1$~eV${}^2$ are ruled out at 90\% C.L. This result improves by more than an order of magnitude previous limits on $\Delta m^2$ derived from electron-neutrino oscillation experiments at accelerators.
