Variational calculations with improved energy functionals in gauge theories

C. Heinemann, E. Iancu, C. Martin +1

For a SU(N) Yang-Mills theory, we present variational calculations using gaussian wave functionals combined with an approximate projection on gauge invariant states. The projection…

Spectroscopy at B-factories Using Hard Photon Emission

M. Benayoun, S. I. Eidelman, V. N. Ivanchenko +1

The process of hard photon emission by initial electrons (positrons) at B-factories is discussed. It is shown that studies of the bottomonium spectroscopy will be feasible for the…

On the direct evidence of time-reversal non-invariance in the $K^{0} - K ˉ^{0}$ system

Andre Rouge

The measurements of the CP violation parameters by the CPLEAR experiment are reviewed. It is shown that attempts to prove T-violation from the semileptonic asymmetries are flawed b…

Precision determination of the pi-N scattering lengths and the charged pi-NN coupling constant

T. E. O. Ericson, B. Loiseau, A. W. Thomas

We critically evaluate the isovector GMO sumrule for the charged $π N N$ coupling constant using recent precision data from $π^{-}$ p and $π^{-}$ d atoms and with careful attention to sys…

A VMD Based, Nonet and SU(3) Symmetry Broken Model For Radiative Decays of Light Mesons

M. Benayoun

We present a VMD based model aiming to describe all radiative decays of light mesons. We show that the SU(3) breaking mechanism proposed by Bando, Kugo and Yamawaki (BKY), suppleme…

VMD, the WZW Lagrangian and ChPT: The Third Mixing Angle

M. Benayoun, L. DelBuono, H. B. O'Connell

We show that the Hidden Local Symmetry Model, supplemented with well-known procedures for breaking flavor SU(3) and nonet symmetry, provides all the information contained in the st…

Production of Like Sign Di-Leptons in p-p Collisions Through Composite Majorana Neutrinos

O. Panella, C. Carimalo, Y. N. Srivastava

The production of Like-Sign-Di-leptons (LSD), in the high energy lepton number violating ( $Δ L = + 2$ ) reaction, p p --> 2jets + l+l+ (l=e,μ,τ) of interest for the experiments to be…

Radiative Decays, Nonet Symmetry and SU(3) Breaking

M. Benayoun, L. DelBuono, S. Eidelman +2

We re-examine the problem of simultaneously describing in a consistent way all radiative and leptonic decays of light mesons (V -> P gamma, P -> V gamma, P -> gamma gamma, V -> e^+…
