Light-cone quark model analysis of radially excited pseudoscalar and vector mesons - art. no. 094020

We present a relativistic constituent quark model to analyze the mass spect rum and hadronic properties of radially excited u and d quark sector mesons . Using a simple Gaussian function as a trial wave function for the variati onal principle of a QCD motivated Hamiltonian, we obtain a mass spectrum co nsistent with the experimental data. To do the same for several observables such as decay constants and form factors, it seems necessary to include bo th Dirac and Pauli form factors on the level of constituent quarks. Taking into account the quark form factors, we thus present the generalized formul as for the rho meson decay constant and form factors as well as the pi gamm a transition form factor. We also predict several hadronic properties for t he radially excited states. [S0556-2821(99)06819-8].
