Measurement of the Antilambda Polarization in nu_mu Charged Current Interactions in the NOMAD Experiment
The NOMAD Collaboration: P.Astier, et al.
TL;DR
This paper reports the first measurement of Antilambda hyperon polarization in neutrino charged current interactions, finding it to be consistent with zero, using data from the NOMAD experiment.
Contribution
It provides the first measurement of Antilambda polarization in neutrino interactions, extending hyperon polarization studies to neutrino experiments.
Findings
Antilambda polarization is compatible with zero.
Analysis used the same method as for Lambda hyperons.
First polarization measurement of Antilambda in neutrino interactions.
Abstract
We present a measurement of the polarization of Antilambda hyperons produced in nu_mu 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 for the case of Lambda hyperons. The Antilambda polarization has been measured for the first time in a neutrino experiment. The polarization vector is found to be compatible with zero.
