| 英文摘要 | We present the first upper-limit measurement of the branching fractions of the isospin-violating transitions chi(c0,2) -> pi(0)eta(c). the measurements are performed using 106 x 10(6) psi(3686) events accumulated with the besiii detector at the bepcii e(+)e(-) collider at a center-of-mass energy corresponding to the psi(3686) mass. we obtained upper limits on the branching fractions at a 90% confidence level of b(chi(c0) -> pi(0)eta(c)) < 1.6 x 10(-3) and b(chi(c2) -> pi(0)eta(c)) < 3.2 x 10(-3). |
