Abstract：
Low-energy scattering of D^*+and D⁰₁meson is studied using quenched lattice QCD with improved lattice actions on anisotropic lattices. The threshold scattering parameters, namely the scattering length a₀and the effective range r₀, for the s-wave scattering in J^P=0^－channel are extracted: a₀=2.52(47) fm and r₀=0.7(1) fm. It is argued that, albeit the interaction between the two charmed mesons being attractive, it is unlikely that they can form a shallow bound state in this channel. Our calculation provides some useful information on the nature of the newly discovered resonance-like structure Z⁺(4430) by the Belle Collaboration.
