Abstract

Recently Babar Collaboration reported a new csˉc\bar{s} state DsJ(2860)D_{sJ}(2860) and Belle Collaboration observed DsJ(2715)D_{sJ}(2715). We investigate the strong decays of the excited csˉc\bar{s} states using the 3P0^{3}P_{0} model. After comparing the theoretical decay widths and decay patterns with the available experimental data, we tend to conclude: (1) DsJ(2715)D_{sJ}(2715) is probably the 1(13D1)1^{-}(1^{3}D_{1}) csˉc\bar{s} state although the 1(23S1)1^{-}(2^{3}S_{1}) assignment is not completely excluded; (2) DsJ(2860)D_{sJ}(2860) seems unlikely to be the 1(23S1)1^{-}(2^{3}S_{1}) and 1(13D1)1^{-}(1^{3}D_{1}) candidate; (3) DsJ(2860)D_{sJ}(2860) as either a 0+(23P0)0^{+}(2^{3}P_{0}) or 3(13D3)3^{-}(1^{3}D_{3}) csˉc\bar{s} state is consistent with the experimental data; (4) experimental search of DsJ(2860)D_{sJ}(2860) in the channels DsηD_s\eta, DKDK^{*}, DKD^{*}K and DsηD_{s}^{*}\eta will be crucial to distinguish the above two possibilities.
