Self-motion triggers complementary visual and vestibular reflexes supporting image-stabilization and balance. Translation through space produces one global pattern of retinal image motion (optic… (More)

We update the determination of |V us | using semielectronic and semimuonic decays of K mesons. A modest improvement of 15% with respect to its present value is obtained for the error bar of this… (More)

We use SU(3) flavor symmetry to analyze the PP , V P and baryon-antibaryon decays of J/ψ. Both, the SU(3)-invariant and -violating contributions are considered. Particular attention is paid to the… (More)

We study a model with two Higgs doublets where FCNC are allowed at tree-level. In this model, the interactions of charged Higgs with fermions (H ± f ¯ f ′), include a term that is not proportional to… (More)

We have computed the branching ratios of the exclusive pseudoscalar (vector) + tensor modes that are allowed in the decays of the Bc meson. The dominant spectator and annihilation contributions in… (More)

We compute the SUSY effective hamiltonian that describes the |∆S| = 1 semilep-tonic decays of tau leptons. We provide analytical expressions for supersymmetric contribution to τ → u¯ sν τ transition… (More)

The Cabibbo-suppressed non-leptonic decays of B (and D) mesons to final states involving tensor mesons are computed using the non-relativistic quark model of IsgurScora-Grinstein-Wise with the… (More)

Using the vector meson dominance model we get predictions for the Cabibbo-favored τ → ωπ−ντ and τ → φπ−ντ decays. We show how the measurements of these two decays can provide information on the… (More)

A dynamical model based on effective Lagrangians is proposed to describe the bremsstrahlung reaction πN → πNγ at low energies. The ∆(1232) degrees of freedom are incorporated in a way consistent with… (More)
