Measurements of Born cross sections of e+e- ? Ds?+ DsJ- + c. c.

Abstract

The Born cross sections are measured for the first time for the processes e+e-?Ds?+Ds0?(2317)-+c.c. and e+e-?Ds?+Ds1(2460)-+c.c. at the center-of-mass energy s=4.600 GeV, 4.612 GeV, 4.626 GeV, 4.640 GeV, 4.660 GeV, 4.68 GeV, and 4.700 GeV, and for e+e-?Ds?+Ds1(2536)-+c.c. at s=4.660 GeV, 4.680 GeV, and 4.700 GeV, using data samples collected with the BESIII detector at the BEPCII collider. No structures are observed in cross-section distributions for any of the processes. © 2021 authors. Published by the American Physical Society.
