Poles in scattering from forward dispersion relations and revised total cross-section data

José Ramón Peláez, Pablo Rabán, Jacobo Ruiz de Elvira

We present a model-independent calculation of forward dispersion relations and their analytic continuation to the complex plane, using a revised set of total cross-s…

The unintuitive SU(3) flavor and chiral limits of hadron resonances

José Ramón Peláez, Pablo Rabán, Jacobo Ruiz de Elvira

Contrary to naive expectations, poles used to define hadron resonances rigorously in the physical world may not evolve continuously to become degenerate in the SU(3) and chiral…

Dispersive determination of resonances from scattering data

José Ramón Peláez, Pablo Rabán, Jacobo Ruiz de Elvira

We provide a precise, model- and parametrization-independent dispersive determination of the , , , , , , , and…

Nucleon mass: trace anomaly and -terms

Martin Hoferichter, Jacobo Ruiz de Elvira

We give a pedagogical introduction to the origin of the mass of the nucleon. We first review the trace anomaly of the energy-momentum tensor, which generates most of the nucleon ma…

Kaon Physics: A Cornerstone for Future Discoveries

Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153

The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…

Thermal hadron resonances and Ward identities: results for the QCD phase diagram

Angel Gómez Nicola, Jacobo Ruiz de Elvira, Andrea Vioque-Rodríguez

We review recent work regarding the role of light scalar resonances at finite temperature for chiral symmetry and restoration. The results obtained are based on unitarized…
