    Dispersion relations for

    Tobias Isken🇩🇪 · Bastian Kubis🇩🇪 · Sebastian P. Schneider🇩🇪 · Peter Stoffer🇩🇪

    We present a dispersive analysis of the decay amplitude for that is based on the fundamental principles of analyticity and unitarity. In this framework, final-state interactions are fully taken into account. Our dispersive representation relies only on input for the and scattering phase shifts. Isospin symmetry allows us to describe both the charged and neutral decay channel in terms of the same function. The dispersion relation contains subtraction constants that cannot be fixed by unitarity. We determine these parameters by a fit to Dalitz-plot data from the VES and BES-III experiments. We study the prediction of a low-energy theorem and compare the dispersive fit to variants of chiral perturbation theory.

    Rapidity Distributions of Hadrons in Proton-Nucleus Collisions

    H.J. Pirner🇩🇪 · B. Kopeliovich🇩🇪

    We study proton-lead collisions with a new model for the Fock states of the incoming proton. The number of collisions which the proton experiences selects the appropriate Fock state of the proton which generates a multiple of pp-like rapidity distributions. We take as input the pp maximum entropy distributions shifting the respective cm-rapidities and reducing the available energies. A comparison with existing data at 5 TeV is made and results for 8 TeV are presented. We also explore the high multiplicity data in this model.

    White Paper on Nuclear Data Needs and Capabilities for Basic Science

    F.G. Kondev🇺🇸 · M. Thoennessen🇺🇸 · J. Batchelder🇺🇸 · T. Kawano🇺🇸 · J. Kelley🇺🇸 · E. McCutchan🇺🇸 · M. Smith🇺🇸 · A. Sonzogni🇺🇸 · I. Thompson🇺🇸

    The Workshop on Nuclear Data Needs and Capabilities for Basic Science was held at the University of Notre Dame on 10-11 August 2016. The purpose of this targeted workshop was to assemble and prioritize the needs of the nuclear physics research community for data sets, services and capabilities in areas including nuclear structure, nuclear reactions, nuclear astrophysics, fundamental interactions, neutrino physics and nuclear theory. An overview of nuclear data needs and capabilities identified at this meeting are summarized in the present document.
