SUMMARY:Present and future perspectives in Hadron Physics
DESCRIPTION:The Workshop will be held in person from 17 to 19 June 2024\, in Frascati (Italy) in the context of the project STRONG-2020 (http://www.strong-2020.eu/).The objective is to gather a broad Hadron Physics Community\, including both young and experienced researchers. The first day will be dedicated to selected contributions. STRONG-2020 offers an opportunity to cover local and travel expenses for young researchers.During the second and third days\, invited speakers will present their work and perspectives in various areas of Hadron Physics and related fields.  The Workshop will be followed by the STRONG-2020 Annual Meeting organized in Frascati on 20-21 June 2024 and open to a large audience. The Agenda will be soon available and the Registration is possible at the dedicated site here.   This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 824093

SUMMARY:Dark matter in QCD-like theories with a theta vacuum: cosmological and astrophysical implications
DESCRIPTION:Oscar Zapata (Universidad de Antioquia) \nQCD-like theories in which the dark matter (DM) of the Universe is hypothesized to be a thermal relic in the form of a dark pion has been extensively investigated\, with most studies neglecting the CP-violating θ-angle associated with the topological vacuum. We point out that a non-vanishing θ could potentially trigger resonant number-changing processes giving rise to the observed relic density in agreement with perturbative unitarity as well as observations of clusters of galaxies. This constitutes a novel production mechanism of MeV DM and an alternative to those relying on the Wess-Zumino-Witten term. Moreover\, for specific meson mass spectra\, similar resonant scatterings serve as a realization of velocity-dependent self-interacting DM without a light mediator. Explicit benchmark models are presented together with a discussion of possible signals.
