| 英文摘要 | Based on e(+)e(-) annihilation data samples collected with the besiii detector at the bepcii collider at 13 center-of-mass energies from 4.008 to 4.600 gev, measurements of the born cross section of e(+)e(-) -> p (p) over bar pi(0) are performed. no significant resonant structure is observed in the measured energy dependence of the cross section. the upper limit on the born cross section of e(+)e(-) -> y (4260) -> p (p) over bar pi(0) at the 90% c. l. is determined to be 0.01 pb. the upper limit on the ratio of the branching fractions b(y(4260) -> p (p) over bar pi(0))/b(y(4260) -> pi(+)pi(-) j/psi) at the 90% c. l. is determined to be 0.02%.
