Masses and couplings of vector mesons from the pion electromagnetic, weak, and πγtransition form factors
D. Melikhov, O. Nachtmann, V. Nikonov +1
We analyse the pion electromagnetic, charged-current, and transition form factors at timelike momentum transfers , GeV, using a dispersion approach. We d…
The pion form factor at timelike momentum transfers in a dispersion approach
D. Melikhov, O. Nachtmann, T. Paulus
We consider a model with , , and gauge-invariant couplings and obtain the pion form factor at timelike momentum transfers by resummation of pion and kaon loops…
Inelastic diffractive scattering in nonperturbative QCD
H. G. Dosch, O. Nachtmann, T. Paulus +1
We examine diffractive proton-proton scattering p p -> p X and photo- and electroproduction of ρ^0 mesons γ^(*) p -> ρ^0 X, where X denotes a proton or a final state, into which th…
Inelastic diffractive proton-proton scattering in nonperturbative QCD
Otto Nachtmann, Timo Paulus
We examine diffractive proton-proton scattering. Using a functional integral approach we derive the scattering amplitudes, which are governed by the expectation value of lightlike…
