Measurements of Born Cross Sections of $e^{+}{e}^{-}\to D_s^{\ast +}{D}_{sJ}^{-}+c.c.$

Abstract

The Born cross sections are measured for the first time for the processes $e^{+}{e}^{-}\to D_s^{\ast +}{D}_{s0}^{\ast }(2317{)}^{-}+c.c.$ and $e^{+}{e}^{-}\to D_s^{\ast +}{D}_{s1}(2460{)}^{-}+c.c.$ at the center-of-mass energy $\sqrt{s}=$ 4.600~GeV, 4.612~GeV, 4.626~GeV, 4.640~GeV, 4.660~GeV, 4.68~GeV, and 4.700~GeV, and for $e^{+}{e}^{-}\to D_s^{\ast +}{D}_{s1}(2536{)}^{-}+c.c.$ at $\sqrt{s}=$ 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.
