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

High Energy Physics - Phenomenology 2022-02-16 v1

Abstract

A polarization analysis is performed for the recent observation of ZcsZ_{cs} exotic state in the e+ee^+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 ZcsZ_{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 ZcsZ_{cs} spin scenarios.
