Constraining $\hat{I}{»}_{B_s}$ by $B_s\to γ^*$ and $B_s\to \ddot{I}•$ form factors

Mikhail A. Ivanov, Dmitri Melikhov, Silvano Simula

We calculate the form factors $F_V(q^2,q^{\prime 2})$ and $F_{TV}(q^2,q^{\prime 2})$ describing the $B_s\to γ^*$ transition induced by the vector and tensor weak currents in a broad range of va…
