报告摘要：
In this talk, I will present a novel effective-field-theory-based approach for extracting two-body scattering information from finite volume energies. By explicitly incorporating one-pion exchange, we overcome the challenging left-hand cut problem in the Lüscher's method and can handle finite volume energy levels both below and above the left-hand cut. Additionally, we utilize the plane wave basis instead of the conventional partial wave expansion to account for partial wave mixing effects resulting from rotational symmetry breaking in a cubic box. Applied to the lattice data for DD^* scattering at a pion mass of 280 MeV, it reveals the significant impact of the one-pion exchange interaction. The pole position of the T_cc (3875)^+ state, extracted from the lattice data, appears to be consistent with a near-threshold resonance.
