Semileptonic transitions: B(s) → π(K); Ds → K; D → π,K; and K → π

Continuum Schwinger function methods for the strong-interaction bound-state problem are used to arrive at a unified set of parameter-free predictions for the semileptonic K→π, D→π,K and Ds→K, B(s)→π(K) transition form factors and the associated branching fractions. The form factors are a leading sou...
