초록

We report a study of the processes e(+)e(-)-> J/psi D-(*())(D) over bar (()*()). In J/psi D*(D) over bar (()*()) we observe a significant enhancement in the D*(D) over bar (()*()) invariant mass spectrum, which we interpret as a new charmoniumlike state and denote X(4160). The X(4160) parameters are M=(4156(-20)(+25)+/- 15) MeV/c(2) and Gamma=(139(-61)(+111)+/- 21) MeV. We also report a new measurement of the X(3940) mass and width: M=(3942(-6)(+7)+/- 6) MeV/c(2) and Gamma=(37(-15)(+26)+/- 8) MeV. The analysis is based on a 693 fb(-1) data sample recorded near the Upsilon(4S) resonance by the Belle detector at the KEKB asymmetric-energy collider.
