Newly observed D{sub sJ}(3040) and the radial excitations of P-wave charmed-strange mesons

Inspired by the newly observed D{sub sJ}(3040){sup +} state, in this work we systemically study the two-body strong decays of P-wave charmed-strange mesons with the first radial excitation. Under the assignment of 1{sup +}(j{sup P}=(1/2){sup +}), i.e. the first radial excitation of D{sub s1}(2460){sup +}, we find that the width of D{sub sJ}(3040){sup +} is close to the lower limit of the BABAR measurement. This indicates that it is reasonable to interpret D{sub sJ}(3040){sup +} as the first radial excitation of D{sub s1}(2460){sup +}. Our calculation further predicts that 0{sup -}+1{sup -} channels, e.g., D{sup +}K*{sup 0}, D{sup 0}K*{sup +}, and D{sub s}{sup +}{phi}, are important for the search for D{sub sJ}(3040){sup +}. To help future experiments find the remaining three P-wave charmed-strange mesons with the first radial excitation, we present the predictions for the strong decays of these three P-wave charmed-strange mesons.
