We present the results of a search for nu(mu) --> nu(e) oscillations in the NOMAD experiment at CERN. The experiment looked for the appearance of nu(e) in a predominantly nu(mu) wide-band neutrino beam at the CERN SPS. No evidence for oscillations was found. The 90% confidence limits obtained are Deltam(2) < 0.4 eV(2) for maximal mixing and sin(2) (20) < 1.4 x 10(-3) for large Deltam(2). This result excludes the LSND allowed region of oscillation parameters with Deltam(2) greater than or similar to 10 eV(2). (C) 2003 Elsevier B.V. All rights reserved.
