RT Journal Article T1 𝐷*β’π·β’πœ‹ and 𝐡*β’π΅β’πœ‹ couplings from Dyson-Schwinger equations framework A1 Xu, Yinzhen A1 Raya, KhΓ©pani AB Employing a unified Dyson-Schwinger/Bethe-Salpeter equations approach, we calculate the strong decay couplings 𝐷*β’π·β’πœ‹ and 𝐡*β’π΅β’πœ‹ within the so-called impulse-approximation in the moving frame. The 𝐡*β’π΅β’πœ‹ estimation is reported for the first time based on a PoincarΓ© invariant computation of the associated Bethe-Salpeter amplitudes. Our predictions yield 𝑔𝐷*β’π·β’πœ‹ =16.2⁒2+0.03βˆ’0.01 and 𝑔𝐡*β’π΅β’πœ‹ =40.0⁒9+1.51βˆ’1.37, along with corresponding static strong couplings of ^𝑔𝐷 =0.5⁒5+<0.01βˆ’<0.01, ^𝑔𝐡 =0.5⁒0+0.02βˆ’0.02, which are consistent with recent experimental and lattice data.
