Axial and electromagnetic observables of hyperons in 2-flavor chiral perturbation theory
Axial electromagnetic observables of hyperons 2-flavor chiral perturbation theory
2011/1/7
Two-flavor chiral expansions provide a useful perturbative framework to study hadron properties.
Such expansions should exhibit marked improvement over the conventional three-flavor chiral
expansion...
