Measurement of the Born cross sections for e+e−→D+sDs1(2460)−+c.c. and e+e−→D*+sDs1(2460)−+c.c.

• The processes e(+)e(-) -> D-s(+) D-s1 (2460)(-) + c.c. and e(+) e(-) -> D-s*(+) 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(-) -> 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(-) -> D-s*(+) D-s1 (2460)(-)+ c.c. at root s = 4.590 GeV and 4.600 GeV are measured. No obvious charmonium or charmoniumlike structure is seen in the measured cross sections.
