A relation between the charge radii of π+, K+, K0 derived by the general QCD parametrization
Description
We derive, using the general QCD parametrization, the approximate relation r2(π+) - r2(K+) ≅ -r2(K0) where the r's are the charge radii. The relation is satisfied but the experimental errors are still sizeable. The derivation is similar to (but even simpler than) that for r2(p) - r2(n) ≅ r2(Δ+) (orig.)
