Abstract

A search for exotic Θ⁺ baryon via Θ ⁺→p+K⁰ _S decay mode in the NOMAD ν_μN 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 2.13×10^-3 per neutrino interaction.

AB - A search for exotic Θ+ baryon via Θ +→p+K0 S decay mode in the NOMAD νμN 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 xF 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 2.13×10-3 per neutrino interaction.
