THE SEARCH FOR INCLUSIVE ELECTRON-NEUTRINO OSCILLATIONS ON THE SERPUKHOV 70 GEV ACCELERATOR WITH THE IHEP-JINR NEUTRINO DETECTOR

The experiment on the search for inclusive electron neutrino oscillati ons is being carried out at the special neutrino beam of the Serpukhov 70 GeV accelerator using the IHEP-JINR neutrino detector. The short d ecay cavity of the neutrino beam makes it possible to search for oscil lations analyzing the shape of the distribution of events using the va riable LIE, where L is the distance from the point of origin to the po int of interaction of neutrino, E is the neutrino energy. The data of the two runs are processed and analysed. The best fit is obtained with Delta m(2) = 300 eV(2) and sin(2) 2 Theta = 0.144, but the chi(2) doe s not differ much for the hypothesis of no oscillations (within one st andard deviation). This gives the limits on the oscillation parameters of sin(2) 2 Theta < 0.115 at Delta m(2) = 175 eV(2) (90% C.L.). For r easons outlined in the text, we believe this limit to be better or mor e reliable than earlier limits published by other experiments.
