Abstract:
The cross section for e(+)e(-)->pi(+)pi(-)psi(2S) between threshold and root s=5.5 GeV is measured using 673 fb(-1) of data on and off the Upsilon(4S) resonance collected with the Belle detector at KEKB. Two resonant structures are observed in the pi(+)pi(-)psi(2S) invariant-mass distribution, one at 4361 +/- 9 +/- 9 MeV/c(2) with a width of 74 +/- 15 +/- 10 MeV/c(2), and another at 4664 +/- 11 +/- 5 MeV/c(2) with a width of 48 +/- 15 +/- 3 MeV/c(2), if the mass spectrum is parametrized with the coherent sum of two Breit-Wigner functions. These values do not match those of any of the known charmonium states.
