Planar Property and Long-range Azimuthal Correlation in $e^{+}{e}^{-}$ Annihilation

Xuan Chen, Yuesheng Dai, Shi-Yuan Li +2

The $e^{+}{e}^{-}$ annihilation of unpolarized beams is free from initial hadron states or initial anisotropy around the azimuthal angle, hence ideal for studying the correlations of dyn…
