pre-print
In this exploratory lattice study, low-energy scattering of the (DD̅^*)^± meson system is analyzed using lattice QCD with N_f=2 twisted mass fermion configurations with three pion mass values. The calculation is performed within single-channel Lüscher's finite-size formalism. The threshold scattering parameters, namely the scattering length a_0 and the effective range r_0, for the s-wave scattering in J^P=1^+ channel are extracted. For the cases in our study, the interaction between the two
