An evaluation is made of the relative contributions of 2K and 2 pi intermediate states to the isovector part of the nucleon's electromagnetic form factor. Dispersion theory is used, and spin and unphysical branch cuts are neglected. It is assumed that the K meson and the nucleon, N, are coupled indirectly through the K-pi and pi-N couplings only. Approximate integrations are carried out for different limiting cases. With the exception of situations where there is not a well-defined trend, all cases show that the 2K-state contribution to the nucleon vector form factor is small. Maximum cross sections and resonance energies for the processes pi pi yields pi pi and pi pi yields KK are also evaluated. (Author).

It is shown that the 4pi intermediate state in pi-pi scattering plays an important role in determining the position and perhaps even the existence of the pi-pi resonance. This large effect occurs by virtue of the pi resonance. Quantitative estimates are given. The effect of this result on the nucleon form factors is briefly discussed and a simple model for these functions is proposed. The possibility of higher energy pion resonances is also considered.

This first open access volume of the handbook series contains articles on the standard model of particle physics, both from the theoretical and experimental perspective. It also covers related topics, such as heavy-ion physics, neutrino physics and searches for new physics beyond the standard model. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access

Filling the gap in the literature on low-energy quark models, The Quark Confinement Model of Hadrons investigates confinement effects in the low-energy regions of particle physics using the methods of nonlocal quantum field theory. It also elucidates their role in describing microscopic quantities that characterize hadron-hadron interactions. The authors present a quark confinement model to describe the low-energy physics of light hadrons. Hadrons are treated as collective colorless excitations of quark-gluon interactions while the quark confinement is to be provided by averaging over gluon backgrounds. The model is shown to reproduce the low-energy relations of chiral theory in the case of null momenta and, in addition, allow the researcher to obtain more sophisticated hadron characteristics, such as slope parameters and form factors. Presenting a unified view on a number of low-energy phenomena, The Quark Confinement Model of Hadrons enables an understanding of problems related to the treatment of large distances within quantum chromodynamics.
