摘要：
In this paper, we perform a combined study of 2S and 1D open-charm mesons with natural spin-parity. Our results indicate that D-1(*)(2600)/D-s1(*)(2700) and D-1(*)(2760)/D-s1(*)(2860) are predominantly the 2(3)S(1) and 1(3)D(1) charmed/charmed-strange mesons, respectively, while D-3(*)(2760)/D-s3(*)(2860) can be regarded as the 1(3)D(3) charmed/charmed-strange mesons. In addition, some typical ratios of partial widths of the discussed natural states are predicted, by which future experiments can test these assignments, especially for the 2S-1D mixing scheme existing in D-1(*)(2600)/D-1(*)(2760) and D-s1(*)(2700)/D-s1(*)(2860).
