| 英文摘要 | Low-energy scattering of D*(+) and (D) over bar (0)(1) meson is studied using quenched lattice QCD with improved lattice actions on anisotropic lattices The threshold scattering parameters, namely the scattering length a(0) and the effective range r(0), for the s-wave scattering in J(P) = 0(-) channel are extracted a(0) = 2 52(47) fm and r(0) = 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 |
