Measurement of the Born cross sections for e + e − → D s + D s 1 ( 2460 ) − + c . c . and e + e − → D s + D s 1 ( 2460 ) − + c . c

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