    Threshold \(\pi ^-\) photoproduction on the neutron

    Recent data from the PIONS@MAX-lab Collaboration, measuring the total cross section of the incoherent pion photoproduction reaction, \(\gamma d\rightarrow \pi ^- pp\) γ d → π - p p , near threshold, have b...

    The multiple-scattering series in pion-deuteron scattering and the nucleon-nucleon potential: perspectives from effective field theory

    Important contributions to meson-nucleus scattering are produced by terms in the multiple-scattering series, which is defined as the sum of all diagrams where the meson scatters back and forth between a pair o...

    Interplay of quark and meson degrees of freedom in a near-threshold resonance

    We investigate the interplay of quark and meson degrees of freedom in a physical state representing a near-threshold resonance for the case of a single continuum channel. We demonstrate that such a near-thresh...

    Evidence for a backward peak in the γd → π0d cross section near the η threshold

    High-quality cross sections for the reaction γd → π0 d have been measured using the CLAS at Jefferson Lab over a wide energy range near and above the η-meson photoproduction threshold. At ...

    Towards a field theoretic understanding of NN → NNπ

    We study the production amplitude for the reaction NN → NNπ up to next-to-leading order in chiral perturbation theory using a counting scheme that takes into account the large scale introduced by the initial mome...

    The radiative decays φ↦γa0/f0 in the molecular model for the scalar mesons

    We investigate the radiative decays of the φ-meson to the scalar mesons a0(980) and f0(980). We demonstrate that, contrary to earlier claims, these decays should be of the same order of magnitude for a molecular ...

    On the reaction pp → ppη near the threshold

    The reaction pp → ppη near the kinematical threshold is considered in the framework of the model, which includes the pp final states interaction (FSI). The Coulomb and strong effects of the pp FSI are calculated ...
