Spin and polarization analysis of $Z_{cs}$ state

Abstract

A polarization analysis is performed for the recent observation of $Z_{cs}$ exotic state in the $e^{+}{e}^{-}$ annihilation experiment with motivation for measuring its spin quantum number in the future. Starting with the unpolarized electron and positron beam, the polarization transfer to the $Z_{cs}$ state and its decay angular distribution patterns are investigated. Some observables are suggested for determination of the spin parity quantum numbers. An ensemble of Monte-Carlo events are used to show some moment distributions special for manifestation of the different $Z_{cs}$ spin scenarios.
