N2 - The processes 푒+⁢푒−→Δ++⁢ ¯Δ−− and 푒+⁢푒−→Δ++⁢¯푝⁢휋−+c.c. are studied for the first time with 179 pb−1 of 푒+⁢푒− annihilation data collected with the BESIII detector at center-of-mass energies from 2.3094 to 2.6464 GeV. No significant signal for the 푒+⁢푒− →Δ++⁢¯Δ−− process is observed and the upper limit of the Born cross section is estimated at each energy point. For the process 푒+⁢푒−→Δ++⁢¯푝⁢휋−+c.c., a significant signal is observed at center-of-mass energies near 2.6454 GeV and the corresponding Born cross section is reported.
