Simple Description of Pion-Pion Scattering to 1 GeV
Masayasu Harada, Francesco Sannino, Joseph Schechter
Motivated by the 1/Nc expansion, we present a simple model of pion-pion scattering as a sum of a `current-algebra' contact term and resonant pole exchanges. The model preserves cro…
Effects of Symmetry Breaking on the Strong and Electroweak Interactions of the Vector Nonet
Masayasu Harada, Joseph Schechter
Starting from a chiral invariant and quark line rule conserving Lagrangian of pseudoscalar and vector nonets we introduce first and second order symmetry breaking as well as quark…
Heavy Quark Solitons: Towards Realistic Masses
J. Schechter, A. Subbaraman, S. Vaidya +1
A generalization of the effective meson Lagrangian possessing the heavy quark symmetry to finite meson masses is employed to study the meson mass dependence of the spectrum of S--…
Exploring $\pp$ scattering in the $\1N$ picture
F. Sannino, J. Schechter
In the large approximation to , the leading $\pp$ scattering amplitude is expressed as the sum of an infinite number of tree diagrams. We investigate the possibility tha…
