Study of radially excited Ds(21S0) and Ds(3P)

The unobserved J(P) =0(-) radial excitation D-s(2(1)S(0)) is anticipated to have mass 2650 MeV (denoted as D-s(2650)). Study of hadronic production is an important way to identify highly excited states. We study hadronic production of D-s(2650) from higher excited resonances in a P-3(0) model. Relevant hadronic partial decay widths are found to be very small, which implies it is difficult to observe D-s(2650) in hadronic decays of higher excited resonances. Hadronic decay widths of radially excited D-s(3P) have also been estimated. The total decay widths of four D-s(3P) are large, but the branching ratios in the D-s(2650)eta channel are very small, which implies that it seems impossible to observe D-s(2650) in hadronic decays of D-s(3P). The dominant decay channels of the four Ds(3P) have been pointed out, and D-1(2420), D-1(2430), D-2* (2460), D(2550), D(2600), (1(1)D(2))D(2750) and D-3* (2760) are possible to observe in hadronic production from D-s(3P).
