The composite nature of baryons manifests itself in the existence of a rich spectrum of
excited states, in particular in the important mass region 1–2 GeV for the light-flavoured …

Decays of the neutral and long-lived η and η′ mesons provide a unique, flavor-conserving
laboratory to test low-energy Quantum Chromodynamics and search for new physics …

We have presented a review of the properties of neutrinos and their interactions with matter.
The different (anti) neutrino processes like the quasielastic scattering, inelastic production of …

We review recent progress in the investigation of the electroexcitation of nucleon
resonances, both in experiment and in theory. We describe current experimental facilities …

We show that the recent excess presented by KOTO in their search for KL→ π 0 ν ν¯ may be
due to weakly coupled scalars produced from Kaon decays. We study two concrete …

This review treats the advances in Light Baryon Spectroscopy of the last two decades, which
were mainly obtained by measuring meson-production reactions at photon facilities all over …

The ηN final state is isospin-selective and thus provides access to the spectrum of excited
nucleons without being affected by excited Δ states. To this end, the world database on eta …

The Dalitz decays η→ e+ e− γ and ω→ π 0 e+ e− have been measured in the γ p→ η p and
γ p→ ω p reactions, respectively, with the A2 tagged-photon facility at the Mainz Microtron …

We investigate the thermal cosmology and terrestrial and astrophysical phenomenology of a
sub-GeV hadrophilic dark sector. The specific construction explored in this work features a …
