Probe of anomalous neutrino couplings to W and Z in medium energy setup of a beta-beam facility

Capability of medium energy setup of a beta beam experiment to probe new physics contributions to neutrino-W and neutrino-Z couplings are investigated. We employ the effective lagrangian approach of Buchmuller and Wyler and obtain 95% confidence level limits on neutrino couplings to these gauge bosons without assuming the flavor universality of the coupling of neutrinos. We show that a beta beam facility with a systematic error of 2% can place 10 times more restrictive limit than present one on the deviations from the electron neutrino-Z couplings in the Standard Model.Capability of medium energy setup of a beta beam experiment to probe new physics contributions to neutrino-W and neutrino-Z couplings are investigated.
