Hadronic form factors in QCD and the incompleteness problem in the time-like region
Enrique Ruiz Arriola, Pablo Sanchez-Puertas, Wojciech Broniowski
Hadronic form factors fulfill dispersion relations and superconvergence sum rules for their spectral density as genuine imprints of QCD. We show several instances where these condi…

Particle seismology: mechanical and gravitational properties from parton-hadron duality
Enrique Ruiz Arriola, Wojciech Broniowski
The internal structure of hadrons is characterized by form factors which correspond to matrix elements of currents. Among those, the stress-energy-momentum tensor is a universally…

Magnetic susceptibility of a hot hadronic medium and quark degrees of freedom near the QCD cross-over point
Rupam Samanta, Wojciech Broniowski
The lattice QCD results for the temperature-dependent magnetic susceptibility of the medium below the cross-over temperature are not possible to reconcile with the widely used Hadr…
