英文摘要The a(0)(0)(980)-f(0)(980) mixing intensity has been predicted to be in the range of 0.01 to 0.2 by various theoretical models, but it lacks firm experimental observation. We examine the possibility of extracting the a(0)(0)(980)-f(0)(980) mixing from the J / psi -> phi f(0)(980) -> phi a(0)(0)(980) reaction at the upgraded Beijing electron positron collider with the BESIII detector. While the branching ratio of this process through the a(0)(0)(980)-f(0)(980) mixing is expected to be about O(10(-6)), similar to the estimated total amount from two background reactions J/psi -> gamma(*)-> phi a(0)(0)(980) and J/psi -> K-*(K) over bar +c.c. -> phi a(0)(0)(980), the peak width from the a(0)(0)(980)-f(0)(980) mixing is about 8 MeV, much smaller than that from other mechanisms. With 10(9) J/psi events at BESIII, the a(0)(0)(980)-f(0)(980) mixing intensity is expected to be unambiguously and precisely measured.
