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 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 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 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)

We consider the effects of anomalous magnetic dipole moments of vector mesons in the decay distribution of photons emitted in two-pseudoscalar decays of charged vector mesons. By choosing a… (More)

Two-body non-leptonic decays of B mesons into PT and V T modes are calculated using the non-relativistic quark model of Isgur et al.. The predictions obtained for B → πD 2, ρD 2 are a factor of 3 ∼ 5… (More)

Neutron beta decay and the current determination of V ud. Abstract Measurements of neutron beta decay observables required to determine |V ud | are reaching the 0.1% accuracy. In this paper we review… (More)
