چکیده
Final-state interaction phase difference in J/ψ → ρη and ωη decays Abstract It is shown that the study of the ω − ρ 0 interference pattern in the J/ψ → (ρ 0 + ω)η → π + π − η decay provides the evidence for the large (nearly 90 •) relative phase between the one-photon and the three-gluon decay amplitudes.

Taking advantage of large top production rates at the LHC, the leptonic final states with J/ψ are explored for a precise determination of the top quark mass. The top is partially reconstructed by combining the isolated lepton from the W with the J/ψ from the decays of the corresponding b-quark. The method relies, to a large extent, on the proper Monte-Carlo description of top production and dec...

The CP violating asymmetries for Cabibbo suppressed charged D meson decays in the standard model are estimated in the factorized approximation, using the two-loop effective hamiltonian and a model for final state interactions previously tested for Cabibbo allowed D decays. No new parameters are added. The predictions are larger than expected and not too far from the experimental possibilities.

We provide succinct covariant amplitude decompositions of 2-body weak hadronic decays, with which to compare data, including exclusive rates, helicity amplitudes and polarizations. For weak decays, the systematic dependence of these amplitudes on masses and quantum numbers of participating particles are determined within a factor of about two by the CKM angles and the Fermi constant so theoreti...
