摘要：
We calculate J/iii triangular flow in high energy nuclear collisions. The charmonium motion in medium is controlled by a transport equation with loss and gain terms, and the evolution of the hot medium is governed by a single-shot hydrodynamic equation with a triangularly deformed initial condition. In comparison with the elliptic flow v2, the triangular flow v3 comes almost completely from the charmonium regeneration in the quark gluon plasma and therefore is more sensitive to the medium properties.
