Abstract

In this exploratory lattice study, low-energy near threshold scattering of the (Dˉ1D)±(\bar{D}_1 D^{*})^\pm meson system is analyzed using lattice QCD with Nf=2N_f=2 twisted mass fermion configurations. Both s-wave (JP=0J^P=0^-) and p-wave (JP=1+J^P=1^+) channels are investigated. It is found that the interaction between the two charmed mesons is attractive near the threshold in both channels. This calculation provides some hints in the searching of resonances or bound states around the threshold of (Dˉ1D)±(\bar{D}_1 D^{*})^\pm system.
