    An experimental program with high duty-cycle polarized and unpolarized positron beams at Jefferson Lab

    Positron beams, both polarized and unpolarized, are identified as important ingredients for the experimental programs at the next generation of lepton accelerators. In the context of the hadronic physics progr...

    Electron-Ion Collider: The next QCD frontier

    This White Paper presents the science case of an Electron-Ion Collider (EIC), focused on the structure and interactions of gluon-dominated matter, with the intent to articulate it to the broader nuclear scienc...

    Transverse-momentum-dependent parton distribution/fragmentation functions at an electron-ion collider

    We present a summary of a recent workshop held at Duke University on Partonic Transverse Momentum in Hadrons: Quark Spin-Orbit Correlations and Quark-Gluon Interactions. The transverse-momentum-dependent parto...

    Twist-3 single-spin asymmetries in semi-inclusive deep-inelastic scattering

    The single-spin asymmetries for a longitudinally polarized lepton beam or a longitudinally polarized nucleon target in semi-inclusive deep-inelastic scattering are twist-3 observables. We study these asymmetri...

    Dispersion relation formalism for virtual Compton scattering off the proton

    We present in detail a dispersion relation formalism for virtual Compton scattering (VCS) off the proton from threshold into the Δ(1232)-resonance region. Such a formalism can be used as a tool to extract the ...

    Dispersion Theoretical Analysis of the Nucleon Spin Polarizabilities

    The spin polarizabilities of the nucleon have been calculated from pion photoproduction data using forward dispersion relations. The feasibility of an experimental determination of these structure constants is...

    Generalized polarizabilities of the nucleon studied in the linear sigma model (II)

    In a previous paper virtual Compton scattering off the nucleon has been investigated in the one-loop approximation of the linear sigma model in order to determine the 3 scalar generalized polarizabilities. We ...

    Generalized polarizabilities of the nucleon studied in the linear sigma model

    The generalized polarizabilities of the nucleon have been calculated in the one-loop approximation of the linear sigma model in the limit of infinite sigma mass. In particular, we have investigated the spin-in...
