Light-light and heavy-light mesons spectra from nonperturbative QCD
A. V. Nefediev
Properties of light-light mesons are described by the effective Hamiltonian with spinless quarks derived from QCD. The spectrum is computed by the WKB method and shown to reproduce…
Testing CPT invariance by using C-even neutral-meson--antimeson correlated states
G. V. Dass, W. Grimus, L. Lavoura
We consider the decays of a correlated neutral-meson--antimeson state with C-parity +1. We show that there is CPT noninvariance in the mixing of the neutral mesons if, for any two…
Neutrino Magnetic Moment Solution for the Solar Neutrino Problem and the SNO Experiment
Joao Pulido
The motivations for the magnetic moment solution to the solar neutrino problem are briefly reviewed and the expected values for a number of observables to be measured by the SNO ex…
Cold Dark Matter detection in SUSY models at large tan(beta)
M. E. Gomez, J. D. Vergados
We study the direct detection rate for SUSY cold dark matter (CDM) predicted by the minimal supersymmetric standard model with universal boundary conditions and large values for ta…
Phenomenology of Supersymmetric Theories with and without R-Parity
J. C. Romao
We review supersymmetry models with and without R-parity. After briefly describing the Minimal Supersymetric Standard Model and its particle content we move to models where R-parit…
News about nu's
E. Kh. Akhmedov
We review new results in neutrino physics, including the latest data of the Super-Kamiokande, SNO and K2K experiments.
