Abstract: Newly observed two charmed-strange resonances, Ds1∗(2860) and Ds3∗(2860) , are investigated by calculating their Okubo–Zweig–Iizuka-allowed strong decays, which shows that they are suitable candidates for the 13D1 and 13D3 states in the charmed-strange meson family. Our study also predicts other main decay modes of Ds1∗(2860) and Ds3∗(2860) , which can be accessible at the future experiment. In addition, the decay behaviors of the spin partners of Ds1∗(2860) and Ds3∗(2860) , i.e., 1D(2-) and 1D′(2-) , are predicted in this work, which are still missing at present. The experimental search for the missing 1D(2-) and 1D′(2-) charmed-strange mesons is an intriguing and challenging task for further experiments.
