英文摘要	We perform a full amplitude analysis of the process e(+)e(-)-> j/psi d (d) over bar, where d refers to either d-0 or d+. a new charmoniumlike state x*(3860) that decays to d (d) over bar is observed with a significance of 6.5 sigma. its mass is (3862(-32)(+26) (+40)(-13) )mev= c(2), and its width is (201(-67) (+154)(-82) (+88)) mev. the j(pc) = 0(++) hypothesis is favored over the 2(++) hypothesis at the level of 2.5s. the analysis is based on the 980 fb(-1) data sample collected by the belle detector at the asymmetric-energy e(+)e(-)collider kekb.
