摘要A combined fit is performed to the BABAR and Belle measurements of the e(+)e(-)->pi(+)pi(-)psi(2S) cross sections for center-of-mass energy between threshold and 5.5 GeV. The resonant parameters of the Y(4360) and Y(4660) are determined. The mass is 4355(-10)(+9)+/- 9 MeV/c(2) and the width is 103(-15)(+17)+/- 11 MeV/c(2) for the Y(4360), and the mass is 4661(-8)(+9)+/- 6 MeV/c(2) and the width is 42(-12)(+17)+/- 6 MeV/c(2) for the Y(4660). The production of the Y(4260) in pi(+)pi(-)psi(2S) mode is found to be at 2 sigma level, and B(Y(4260)->pi(+)pi(-)psi(2S))center dot Gamma(+)(e)e(-) is found to be less than 4.3 eV/c(2) at the 90% confidence level, or equal to 7.4(-1.7)(+2.1) eV/c(2) depending on whether it interferes with the Y(4360) constructively or destructively. This information will shed light on the understanding of the nature of the Y states observed in initial state radiation processes.
