| 英文摘要 | Using ethorne-collision data collected with the besiii detector at the bepcii collider corresponding to an integrated luminosity of 5.2 fb(-1) at center-of-mass energies (root s) from 4.009 to 4.600 gev, the process e(+)e(-) -> pi(0)pi(0)psi(3686) is studied for the first time. the corresponding born cross sections are measured and found to be half of those of the reaction e(+)e(-) -> pi(0)pi(0)psi(3686). this is consistent with the expectation from isospin symmetry. furthermore, the dalitz plots for pi(0)pi(0)psi(3686) are accordant with those of pi(0)pi(0)psi(3686) at all energy points, and a neutral analog to the structure in pi(+/-)psi(3686) around 4040 mev/c(2) first observed at root s = 4.416 gev is observed in the isospin neutral mode at the same energy. |
