Molecular interpretation of the Tcc⁺ via deep learning

Abstract

We investigate the nature of the doubly charmed tetraquark candidate T_cc⁺ using a two-pronged approach that combines S-matrix theory with deep learning. The DNN ensemble consistently identifies the LHCb data as a molecular state characterized by an isolated pole on the second Riemann sheet. Guided by the classification result, we perform pole extraction finding a resonance mass M_Tcc⁺ = 3874.783 ± 0.046 [MeV] and a width Γ_Tcc⁺ = 0.098 ± 0.010 [MeV].
