    Collapse to the Center and Ambiguity in the Asymptotic Behavior of the Off-Shell Scattering Amplitude in Singular Three-Body Problems

    Some examples of equations for the there-body problem where there is an oscillating high-momentum behavior are discussed. Specifically, these are (i) the equation in the fixed-center approximation; (ii) the un...

    On the extraction of cross sections for π0 and η photoproduction off neutrons from deuteron data

    We discuss the procedure of extracting the photoproduction cross section for neutral pseudoscalar mesons off neutrons from deuteron data. The main statement is that the final-state-interaction corrections for ...

    Does the multiple-scattering series in the pion-deuteron scattering actually converge?

    It is demonstrated that the well-known answer for the multiple-scattering series (MSS) for a light particle interacting to a pair of static nucleons, calculated in the Fixed Centers Approximation (FCA), works ...

    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...

    Neutron-antineutron oscillations in a trap revisited
