The pion distribution amplitude and the pion-photon transition form factor in a nonlocal chiral quark model
D. Gomez Dumm, S. Noguera, N. N. Scoccola +1
We study the pion Distribution Amplitude (πDA) in the context of a nonlocal chiral quark model. The corresponding Lagrangian reproduces the phenomenological values of the pion mass…
Model analysis of the world data on the pion transition form factor
Santiago Noguera, Vicente Vento
We discuss the impact of recent Belle data on our description of the pion transition form factor based on the assumption that a perturbative formalism and a nonperturbative one can…
Pion-Photon Transition Distribution Amplitudes
A. Courtoy, S. Noguera
The newly introduced Transition Distribution Amplitudes (TDAs) are discussed for the - transitions. Relations between - and - TDAs for different cases are given.…
The Pion-Photon Transition Distribution Amplitudes in the Nambu-Jona Lasinio Model
A. Courtoy, S. Noguera
We define the pion-photon Transition Distribution Amplitudes (TDA) in a field theoretic formalism from a covariant Bethe-Salpeter approach for the determination of the bound state.…
Non local lagrangians(I): the pion
S. Noguera
We define a family of non local and chirally symmetric low energy lagrangians motivated by theoretical studies on Quantum Chromodynamics. These models lead to quark propagators wit…
Generalized parton distributions of the pion in a Bethe-Salpeter approach
S. Noguera, L. Theussl, V. Vento
We calculate generalized parton distribution functions in a field theoretic formalism using a covariant Bethe-Salpeter approach for the determination of the bound-state wave functi…
