摘要：
In this talk we review the theoretical predictions for ratios of branching fractions of (B) over bar (0) decays into 0 and the scalar mesons f(0)(500), f(0)(980), a(0)(980), plus (B) over bar (0)(S) decay into D-0 and kappa(800). We also compare the pi(+)pi(-) production in the scalar channel with that observed in the rho channel and make predictions for the (B) over bar (0)(S) decay into D-0 and K*(892), comparing the strength of this channel with that of kappa(800) production. The work is based on results of the chiral unitary approach where the scalar resonances are generated from the pseudoscalar-pseudoscalar interaction. Up to an arbitrary normalization, the mass distributions and rates for decays into the scalar resonances arc predicted with no free parameters.
