Abstract

We present a measurement of the polarization of Λ̄ hyperons produced in ν_μ charged current interactions. The full data sample from the NOMAD experiment has been analyzed using the same V⁰ identification procedure and analysis method reported in a previous paper [NOMAD Collaboration, Nucl. Phys. B 588 (2000) 3] for the case of Λ hyperons. The Λ̄ polarization has been measured for the first time in a neutrino experiment. The polarization vector is found to be compatible with zero.

N2 - We present a measurement of the polarization of Λ̄ hyperons produced in νμ charged current interactions. The full data sample from the NOMAD experiment has been analyzed using the same V0 identification procedure and analysis method reported in a previous paper [NOMAD Collaboration, Nucl. Phys. B 588 (2000) 3] for the case of Λ hyperons. The Λ̄ polarization has been measured for the first time in a neutrino experiment. The polarization vector is found to be compatible with zero.
