Analysis of strong decays of charmed mesons D2(2460), D0(2560), D2(2740), D1(3000), D2(3000), and their spin partners D1(2680), D3(2760), and D0(3000)

Using the effective Lagrangian approach, we examine the recently observed charm states DJ*(2460), DJ(2560), DJ(2740), DJ(3000), and their spin partners DJ*(2680), DJ*(2760), and DJ*(3000) with JP states 1P322+, 2S120−, 1D522−, 2P121+, and 2S121−, 1D523−, 2P120+ respectively. We study their two body strong decays, coupling constants and branching ratios with the emission of light pseudo-scalar mesons (π,η,K). We also analyze the newly observed charm state D2*(3000) and suggest it to be either 1F(2+) or 2P(2+) state and justify one of them to be the most favorable assignment for D2*(3000). We study the partial and the total decay width of unobserved states D(1F13), Ds(1F13) and Ds(1F12) as the spin and the strange partners of the D2*(3000) charmed meson. The branching ratios and the coupling constants gTH, g˜HH, gYH, g˜SH, and gZH calculated in this work can be confronted with the future experimental data.
