Dual parametrization of generalized parton distributions in two equivalent representations

Dieter Müller, Maxim V. Polyakov, Kirill M. Semenov-Tian-Shansky

The dual parametrization and the Mellin-Barnes integral approach represent two frameworks for handling the double partial wave expansion of generalized parton distributions (GPDs)…

Properties of effective massive Yang-Mills theory in the limit of vanishing vector boson mass

J. Gegelia, U. -G. Meißner

Two-loop corrections to the pole mass of the vector boson and the pole masses and the magnetic moments of fermions are calculated in the framework of an effective field theory of m…

On the pion distribution amplitude. Derivation, properties, predictions

N. G. Stefanis, S. V. Mikhailov, A. V. Pimikov

We provide an in-depth analysis of the distribution amplitude in terms of two different Gegenbauer representations. Detailed predictions for the transition form factor ar…

Vector form factor of the pion in chiral effective field theory

D. Djukanovic, J. Gegelia, A. Keller +2

The vector form factor of the pion is calculated in the framework of chiral effective field theory with vector mesons included as dynamical degrees of freedom. To construct an effe…

Dispersive evaluation of the D-term form factor in deeply virtual Compton scattering

B. Pasquini, M. V. Polyakov, M. Vanderhaeghen

We present a dispersive representation of the D-term form factor for hard exclusive reactions, using unsubtracted -channel dispersion relations. The -channel unitarity relati…

QCD and strongly coupled gauge theories: challenges and perspectives

N. Brambilla, S. Eidelman, P. Foka +46

We highlight the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment. We discuss how the strong interaction is intimately connected to…
