# Form factors in $B \to f_0(980)$ and $D \to f_0(980)$ transitions from dispersion relations

Abstract : Within the dispersion relation approach we give the double spectral representation for space-like and time-like B-> f_0(980) and D-> f_0(980) transition form factors in the full q^2 range. The spectral densities, being the input of the dispersion relations, are obtained from a triangle diagram in the relativistic quark model.
