Gravitational, electromagnetic, and transition form factors of the pion
Wojciech Broniowski, Enrique Ruiz Arriola
Results of the Spectral Quark Model for the gravitational, electromagnetic, and transition form factors of the pion are discussed. In this model both the parton distribution amplit…
Pion quadrupole polarizabilities in the Nambu--Jona-Lasinio model
Brigitte Hiller, Wojciech Broniowski, Alexander A. Osipov +1
We present the results for the pion electromagnetic quadrupole polarizabilities, calculated within the Nambu--Jona-Lasinio model. We obtain the sign and magnitude in agreement with…
Application of chiral quarks to high-energy processes and lattice QCD
Wojciech Broniowski, Enrique Ruiz Arriola
Results of the chiral quark models for the soft matrix elements involving pions and photons, relevant for high-energy processes, are reviewed. We discuss quantities related to the…
Quadrupole polarizabilities of the pion in the Nambu--Jona-Lasinio model
Brigitte Hiller, Wojciech Broniowski, Alexander A. Osipov +1
The electromagnetic dipole and quadrupole polarizabilities of the neutral and charged pions are calculated in the Nambu--Jona-Lasinio model. Our results agree with the recent exper…
Photon interactions and chiral dynamics
Wojciech Broniowski, Alexandr E. Dorokhov, Enrique Ruiz Arriola
Twist-2 components of the real and virtual photon distribution amplitudes are evaluated in several chiral quark models. The results, obtained at the quark model scale, are then evo…
From chiral quark models to high-energy processes
Wojciech Broniowski, Enrique Ruiz Arriola
We show the results of low-energy chiral quark models for soft matrix elements involving pions and photons. Such soft elements, upon convolution with the hard matrix elements, are…
