We estimate the sizes of η - η', η - π0 and η' - π0 mixing angles by solving the Ward-identities in QCD and taking into account SU(3) violation of the quark condensates. Our results are compared with those obtained by treating the quark condens

A strong violation of the Quark Line Rule is observed if we allow the pion nucleon σ term to attain the present experimental value. This in turn indicates the possibility of a large strangeness content in the proton. In this work we have shown that

Using a QCD estimate on the quark-vacuum condensate ratio (ss)0/(uu)0 the authors show, by deriving a sum rule, that the ratio of the meson wavefunction renormalization constants ZK12//Zpi 1/2 may deviate considerably from the SU(3) symmetric value o

The purpose of this paper is to study the bulk properties of nucleon-antinucleon plasma as a function of temperature in the relativistic Hartree approximation which takes into account the contribution of vacuum-fluctuation energy using both Walecka's
