Isospin breaking in low-energy pion-nucleon scattering.
Since isospin symmetry is only approximate, the discrepancy in this relation, D ; fCEX 2 sf1 2 f2dy p 2, is expected to be nonzero. Interesting physics lies in the violation of this relation beyond effects due to the hadronic mass differences and the Coulomb interaction. It is the purpose of this Letter to demonstrate that recent experimental data at low energies require a residual contribution...
متن کاملIsospin-breaking corrections to the pion–nucleon scattering lengths
We analyze isospin breaking through quark mass differences and virtual photons in the pion– nucleon scattering lengths in all physical channels in the framework of covariant baryon chiral perturbation theory. The so-called triangle relation is found to be violated by about 1.5 %. We encounter a substantial isospin-breaking correction to neutral-pion–nucleon scattering beyond Weinberg’s predicti...
متن کاملIsospin violation in pion–nucleon scattering
We construct the complete effective chiral pion–nucleon Lagrangian in the presence of virtual photons to one loop. As an application, we consider strong and electromagnetic isospin violation for scattering of neutral pions off nucleons. We show that for the scattering lengths these isospin violating terms are of the same size as the purely hadronic ones. We also analyze isospin–violating effect...
متن کاملIsospin violation in pion–kaon scattering
We consider strong and electromagnetic isospin violation in near–threshold pion–kaon scattering. At tree level, such effects are small for all physical channels. We work out the complete one–loop corrections to the process π−K+ → π0K0. They come out rather small. We also show that the corresponding radiative cross section is highly suppressed at threshold.
متن کاملPion–nucleon Scattering and Isospin Violation
I discuss low–energy pion–nucleon scattering in the framework of chiral perturbation theory. I argue that using this theoretical method one is able to match the in some cases impressive experimental accuracy (for the low partial waves). I then show how strong and electromagnetic isospin violation can be treated simultaneously. Some first results for neutral pion scattering and the σ–term are gi...
