Search for long range flow-like correlation in hadronic $e^{+}e^{-}$ collisions with Belle
Yu-Chen Chen, C. Lin, Yen-Jie Lee, P. Chang
The enhancement of charged-particle pairs with large pseudorapidity difference and small azimuthal angle difference, often referred to as the "ridge signal", is a phenomenon widely observed in high multiplicity proton-proton, proton-ion and deutron-ion collisions, which is not yet fully understood. In heavy-ion …
