Spin and polarization analysis of the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:msub><mml:mi>Z</mml:mi><mml:mrow><mml:mi>c</mml:mi><mml:mi>s</mml:mi></mml:mrow></mml:msub></mml:math> state
A polarization analysis is performed for the recent observation of ${Z}_{cs}$ exotic state in the ${e}^{+}{e}^{\ensuremath{-}}$ 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 …
