Abstract We present new limits on v{sub e}({bar v}{sub e}){r_arrow}v{sub {tau}}({bar v}{sub {tau}}) and v{sub e}({bar v}{sub e}){r_arrow}v{sub s} oscillations by searching for v{sub e} disappearance in the high-energy wideband CCFR neutrino beam. Sensitivity to v{sub {tau}} appearance comes from {tau} decay modes in which a large fraction of the energy deposited is electromagnetic. The beam is composed primarily of v{sub {mu}}({bar v}{sub {mu}}), but this analysis uses the 2.3{percent} v{sub e}({bar v}{sub e}) component of the beam. Electron neutrino energies range from 30 to 600 GeV and flight lengths vary from 0.9 to 1.4 km. This limit improves the sensitivity of existing limits for v{sub e}{r_arrow}v{sub {tau}} at high {Delta}m{sup 2} and obtains a lowest 90{percent} confidence upper limit in sin{sup 2}2{alpha} of 9.9{times}10{sup {minus}2} at {Delta}m{sup 2}{approximately}125 eV{sup 2}. {copyright} {ital 1998} {ital The American Physical Society}
