[en] Although constructed primarily to aid in the search for neutrino oscillations, NOMAD, a counter experiment exposed to a ν_m beam at the CERN SPS, is capable of making significant contributions to the study of charm quark production in ν_m Deep Inelastic Scattering (DIS) processes. The analysis of such events, however, is dependent upon Monte Carlo simulations of the event kinematics and hence it is essential to understand the behaviour of such simulations. This talk compares data on charm production in the dimuon channel generated by the NOMAD Event Generator (NEGLIB) for an anti-neutrino beam with data collected in the CDHS experiment which ran at CERN in the period 1977-1980. Overall the two sets of data compare well, although some marked differences are observed. Several possible reasons are proposed and discussed

[en] It is shown that energy must be conserved by the dissociation of an elementary particle. The energy deficit by a dissociation behaves as a basic concept. The binding energy of the deuteron is reproduced. 4 refs

[en] The main subject of the GEM meeting were: meson production near threshold, mesic atoms, nuclear resonances, symmetry violation, light ions structure and interactions. Additionally some apparatus problems like electronic equipment and charged particle detector have been discussed.

[en] The method of asymptotic sum rules is used to study phenomenological Lagrangians in Skyrme models. The sum rules are used to obtain relationships for the parameters of the models and to estimate the coupling constants and mass of the scalar meson, which cannot be fixed in the ordinary model approach. It is shown that the sum-rule method and the heavy-meson limit in the effective chiral Lagrangian are in good agreement with each other. 6 refs

[en] We explore charged-Higgs CP-violating effects in an intriguing two-Higgs doublet model which accords special status to the top quark. In this model the heaviness of the top quark originates naturally from the much larger VEV of the second Higgs doublet compared to that of the first. The phenomenology of this model is quite distinct from that of the usual formulations of the two-Higgs doublet model. In particular, the model can easily account for the observed CP violation in the kaon sector even if the CKM matrix is real. The associated non-standard CP phase can be monitored through measurements of the time-dependent CP asymmetry in B→ψK_S in experiments at the upcoming B factories. copyright 1999 The American Physical Society

[en] We present new results on Y and J/Ψ spectroscopy using Lattice NRQCD. Charmonium results at quenched β=5.7 show agreement with experiment within understood systematic errors. We compare bottomonium results at quenched βs 6.0 and 5.7 and show that the 1P-1S splitting scales with Λ_V, provided a correction is applied for the O(a²) errors inherent in the gluon field configurations. There is a clear scale difference between charmonium and bottomonium results in the quenched approximation. We compare quenched results at β=6.0 for bottomonium with those obtained on HEMCGC configurations at β=5.6 using 2 light flavours of dynamical quarks. We show that extrapolations to n_f=3 are consistent with experiment for the ratio of the 2S-1S splitting to that of the 1P-1S. We extract a value for the Y-η_b splitting extrapolated to n_f=3.
