No significant signal for the e+e- - Delta++ Delta over bar -- process is observed and the upper limit of the Born cross section is estimated at each energy point. For the process e+e- - Delta++ p over bar x-- + c:c:, a significant signal is observed at center-of-mass energies near 2.6454 GeV and the corresponding Born cross section is reported.eninfo:eu-repo/semantics/openAccess[No Keywords]Article1087WOS:0011059030000012-s2.0-85178447125N/A10.1103/PhysRevD.108.072010Q1
