Analytic expressions for these quantities are obtained in terms of the parameters of low energy physics (pion decay constant and the pion mass). Good results have been obtained in comparison with my previous works and with the other models. 关键词: Nucleon Sigma-term Linear sigma model DOI: ...
The K 0 , K 0 → 2π amplitudes are represented with emphasis on the recently established value of ′[1]. Linear σ-models as partially integrated effective functionals are analysed in their features which contrast with the nonlinear variant, with respect to the long range aspect of the Δ ...

Its two photon width is found to be $(4.1 \\pm 0.3)$ keV, a value far too large for a gluonic, or even a tetraquark, state. 展开 关键词: High Energy Physics - Phenomenology DOI: http://dx.doi.org/10.1103/PhysRevLett.97.011601 被引量: 11 ...
The $\sigma$-terms are calculated at next-to-leading order in heavy baryon chiral perturbation theory by employing a cutoff regularization. The results do not depend on the cutoff value to the order we are working . The baryon masses and $\sigma_{\pi N}(0)$ are used to perform a leas...
