  1. 91. *Leading Talk* Precise dispersive determination of pion-nucleon scattering and the sigma term

    Talk
    Starting from hyperbolic dispersion relations for the invariant amplitudes of πN scattering together with crossing symmetry and unitarity, we derive and solve a closed system of integral equations for the partial waves of both s-channel (πN → πN) and t-channel (ππ →NN) reactions, called Roy-Steiner equations. Special attention is given to the possible sources of uncertainties and to the...

    Talk
    In my talk, I will focus on the reactions πN->πN and πN->ππN, which are studied at one-loop level in the frameworks of covariant and heavy baryon chiral perturbation theory. Performing combined fits to determine the relevant low-energy constants, predictions are made for various observables. In addition, first attempts to include ∆(1232) and R(1440) as explicit degrees of freedom will be...

    Talk
    Current limits from dark matter direct-detection experiments place a powerful constraint on the parameter space of the Minimal Supersymmetric Standard Model (MSSM). The interpretation of these limits, however, depends sensitively on the hadronic uncertainties associated with the scattering of supersymmetric dark matter particles off nucleons. For spin-independent scattering, we review the...

    Talk
    The Joint Physics Analysis Center gathers theorists working on tools development for the analysis of hadon spectroscopy experiments. Our aim is to provide to experimentalists flexible amplitudes to fit data and easily extract the physics of a specific reaction. I will report on the latest results including pion-nucleon and kaon-nucleon elastic scattering, eta/omega/phi mesons decays in three...
