Study of ${\Lambda}^{0}$ polarization in $ {\nu}_{\mu} N \longrightarrow {\Lambda}^{0}{\mu}^{-}X$ at Low Energies

In MINERvA Experiment (FNAL e938), we study ${\Lambda}^{0}$ polarization in neutrino-nucleon reactions ${\nu}_{\mu} N \longrightarrow {\Lambda}^{0}{\mu}^{-}X$ produced at low energies (1 -4.5 GeV). We present in this work the criteria to identify and select possible ${\Lambda}^{0}$ events, the methodology to study ${\Lambda}^{0}$ polarization, and some preliminary results.
