Production of the Doubly Charged *D Baryon in e*+e*- Annihilation at Energies from 2.3094 to 2.6464 GeV / M.Ablikim, O.Bakina, I.Boyko, G.Chelkov, D.Dedovich, I.Denysenko, P.Egorov, A.Guskov, Y.Nefedov, S.Pogodin, A.Sarantsev, A.Zhemchugov, [a.o.] // Physical Review D [Electronic resource]. – 2023. – Vol.108, No.7. – P.072010. – URL: https://doi.org/10.1103/PhysRevD.108.072010. – Bibliogr.:30.

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