dc.description.abstract | We present a search for electron neutrino appearance from accelerator-produced muon neutrinos in the K2K long-baseline neutrino experiment. One candidate event is found in the data corresponding to an exposure of 4.8x10(19) protons on target. The expected background in the absence of neutrino oscillations is estimated to be 2.4+/-0.6 events and is dominated by misidentification of events from neutral current pi(0) production. We exclude the nu(mu) to nu(e) oscillations at 90% C.L. for the effective mixing angle in the 2-flavor approximation of sin(2)2theta(mue)(similar or equal to1/2sin(2)2theta(13))>0.15 at Deltam(mue)(2)=2.8x10(-3) eV(2), the best-fit value of the nu(mu) disappearance analysis in K2K. The most stringent limit of sin(2)2theta(mue)<0.09 is obtained at Deltam(mue)(2)=6x10(-3) eV(2). | - |
