Study of Hyperon Polarization at T2K, MicroBooNE and MINER$\nu$A

Abstract

Recently, experiments are being performed using high intensity antineutrino beam on nuclear targets at Fermilab and JPARC. The experiments planned with liquid argon TPC (LArTPC) detectors at MicroBooNE, ArgoNeut and the proposed DUNE experiment at the Fermilab can detect pions and protons in coincidence. A measurement of the angular distribution of pions will make it possible to measure the polarization of the hyperons in addition to the cross section measurements. We have presented the results of longitudinal and perpendicular components of polarization of the final hyperon($\varLambda$ and $\varSigma$) produced in quasielastic(QE) antineutrino reactions on nucleons and nuclei. The measurement of polarization components will provide us an alternative method to make precise measurements of axial dipole mass, electric neutron form factor and pseudoscalar form factor in strangeness sector.
