The ρ(2S) and ψ(2S) meson in a double pole QCD Sum Rules    [PDF]

M. S. Maior de Sousa, R. Rodrigues da Silva

We introduce the method of the double pole QCD sum rules and we study the \rho(2S) and \psi(2S) mesons. We get the mass and decay constant of the mesons and show a prediction for the decay constant of the \rho(2S) meson given by (175 \pm 5) MeV.
