We present a phenomenological analysis of the space- and time-like charged kaon electromagnetic form factors in factorized perturbative QCD (pQCD) by employing an analytic model for αs (Q2 ) and an infrared (IR...

With the recent investigations of the g*g*-η(') transition form factor and mixing scheme, we present an updated study of the radiative decays J/ψ→η(')γ in perturbative QCD. The decays are taken as a test ...
