On the and as Bound States and Approximate Nambu-Goldstone Bosons
arXiv:0811.3404 · doi:10.1103/PhysRevD.79.016005
Abstract
We reconsider the two different facets of and mesons as bound states and approximate Nambu-Goldstone bosons. We address several topics, including masses, mass splittings between and and between and , meson wavefunctions, charge radii, and the wavefunction overlap.
