How Good Are the Hard-Pion Calculations near the A 1 Mass?
Paul Horwitz,Probir Roy +1 more
TL;DR: In this article, the Bjorken limit on the primitive vertex function was relaxed in the hard-pion treatment of the A 1 ρπ system and the assumption of single-meson dominance of the propagators was retained.

Soft pion theorems and the Kl3, Kl4 form factors☆
S.M. Berman,Probir Roy +1 more
TL;DR: Theoretical arguments are given, based on current-algebras and the smoothness property of the K l 4 decay formfactors, which imply that the parameter ξ of K l 3 decay has the value - 1 and is approximately constant over the decay region as mentioned in this paper.

Kπ Scattering, κ Meson, and Current Algebra
TL;DR: In this paper, a low-energy-dominated sum rule derived from the algebra of currents was used to determine the scattering lengths for threshold elastic $K\ensuremath{\pi}$ scattering, assuming pionic and kaonic pole dominance hypotheses.
Near κ - K mass degeneracy and the Kl3 form factors
S.M. Berman,Probir Roy +1 more
TL;DR: In this article, the soft pion theorems on the Kl3 and Kl4 matrix elements can be made consistent with the negative values of ξ obtained by the polarization experiments by assuming the existence of a κ-meson with a mass nearly equal to that of the kaon.
