This paper attempts to model the D*π interaction and its impact on the D1(2420) resonance observed in B-meson decays. It aims to reproduce experimental data from LHCb, focusing on the invariant mass distribution of the D*π system. The paper's significance lies in its use of coupled-channel meson-meson interactions to understand the underlying dynamics of D1(2420) and its comparison with experimental results. It also addresses the controversy surrounding the D*π scattering length.
