Measurement of the Born Cross Sections for $e^{+}{e}^{-}\to D_s^{+}{D}_{s1}(2460{)}^{-}+c.c.$ and $e^{+}{e}^{-}\to D_s^{\ast +}{D}_{s1}(2460{)}^{-}+c.c.$

Abstract

The processes $e^{+}{e}^{-}\to D_s^{+}{D}_{s1}(2460{)}^{-}+c.c.$ and $e^{+}{e}^{-}\to D_s^{\ast +}{D}_{s1}(2460{)}^{-}+c.c.$ are studied for the first time using data samples collected with the BESIII detector at the BEPCII collider. The Born cross sections of $e^{+}{e}^{-}\to D_s^{+}{D}_{s1}(2460{)}^{-}+c.c.$ at nine center-of-mass energies between 4.467\,GeV and 4.600\,GeV and those of $e^{+}{e}^{-}\to D_s^{\ast +}{D}_{s1}(2460{)}^{-}+c.c.$ at $\sqrt{s}=$ 4.590\,GeV and 4.600\,GeV are measured. No obvious charmonium or charmonium-like structure is seen in the measured cross sections.
