Threshold Pion Photo- and Electroproduction in Chiral Perturbation Theory
Threshold pion photoand electroproduction off nucleons allow us, by the use of a well-understood probe, to test our understanding of the strong interaction at low energies, i.e. in the non–perturbative regime. Over the last few years, renewed interest in these reactions has emerged. This was first triggered through precise new data on neutral pion photoproduction [1] which lead to a controversy...
متن کاملImproved Description of Threshold Pion Electroproduction in Chiral Perturbation Theory
We investigate neutral pion electroproduction off protons in the framework of heavy baryon chiral perturbation theory. The chiral expansion of the S–wave multipoles E0+ and L0+ is carried out to three orders. There appear several undetermined low– energy constants. Three are taken from a recent study of the new TAPS threshold π0 photoproduction data, one is fixed from the proton Dirac form fact...
متن کاملNear threshold neutral pion electroproduction on deuterium in chiral perturbation theory
Near threshold neutral pion electroproduction on the deuteron is studied in the framework of baryon chiral perturbation theory at next–to–leading order in the chiral expansion. We develop the multipole decomposition for pion production off spin-1 particles appropriate for the threshold region. The existing data at photon virtuality k = −0.1GeV can be described satisfactorily. Furthermore, the p...
متن کاملPion–Pion and Pion–Nucleon Interactions in Chiral Perturbation Theory*
Elastic pion–pion and pion–nucleon scattering are reviewed in the context of chiral perturbation theory. Theoretical results from systematic low–energy expansions to O(p) for ππ and to O(p) for πN are compared with experimental data. Possible future developments are outlined. Talk given at the Workshop on Chiral Dynamics 1997 Mainz, Germany, Sept. 1 5, 1997 To appear in the Proceedings * Work s...
متن کاملPion Scattering in Wilson Chiral Perturbation Theory
We compute the scattering amplitude in Wilson Chiral Perturbation Theory for two flavors. The lattice spacing effects due to the explicit chiral symmetry breaking are kept through O(a2), and we consider the regime where the quark mass m is of order aΛQCD. Analytic expressions for the scattering lengths in different isospin channels are given. As a result of the O(a2) terms the scattering length...
