A search for exotic Θ(+) baryon via Θ(+) -> p + K-S(0) decay mode in the NOMAD v(μ)N data is reported. The special background generation procedure was developed. The proton identification criteria are tuned to maximize the sensitivity to the Θ(+) signal as a function of x(F) which allows to study the Θ(+) production mechanism. We do not observe any evidence for the Θ(+) state in the NOMAD data. We provide an upper limit on Θ(+) production rate at 90% CL as 2.13 x 10(-3) per neutrino interaction..
The experiment was supported by the following funding agencies: Australian Research Council (ARC) and Department of Education, Science, and Training (DEST), Australia; Institut National de Physique Nucléaire et Physique des Particules (IN2P3), Commissariat à l’Energie Atomique (CEA), France; Bundesministerium für Bildung und Forschung (BMBF, contract 05 6DO52), Germany; Istituto Nazionale di Fisica Nucleare (INFN), Italy; Joint Institute for Nuclear Research and Institute for Nuclear Research of the Russian Academy of Sciences, Russia; Fonds National Suisse de la Recherche Scientifique, Switzerland; Department of Energy, National Science Foundation (grant PHY-9526278), the Sloan and the Cottrell Foundations, USA..
