  1. 258. Recent Spin Structure Function Measurements from CLAS at Jefferson Laboratory
    Dr Robert Fersch (Christopher Newport University)
    18/04/2018, 09:00

    The polarized electron accelerator at Jefferson Laboratory (JLab) in Newport News, Virginia, USA yields a robust program for the study of the spin physics of the nucleon. The CLAS detector and longitudinally polarized target in Hall-B at JLab were employed in multiple measurements of spin-structure functions for the proton and neutron in the resonance and DIS regions at beam energies of up to...

    WG6: Spin and 3D structure

    The STAR experiment at the Relativistic Heavy-Ion Collider at Brookhaven National
    Laboratory is carrying out a spin physics program in high-energy polarized proton collisions
    to gain a deeper insight into the spin structure and
    dynamics of the proton.

    The collision of polarized protons at $\sqrt{s}=510\,$GeV opens a new era of spin-flavor
    structure measurements from $W^{+}/W^{-}$ boson...

  3. 175. W Measurement at PHENIX
    Dr Chong Kim (UC Riverside)

    WG6: Spin and 3D structure

    The W measurement at RHIC (Relativistic Heavy Ion Collider) provides unique access to the sea quark polarization of the proton. By measuring decay leptons from parity-violating W bosons, which only coupled to left-handed quarks and right-handed antiquarks, a clean, fragmentation free measurement is possible in addition to natural flavor separation. In this talk, we present status and...

  4. 225. First extraction of transversity from electron-proton and proton-proton data
    Marco Radici

    WG1: Structure Functions and Parton Densities

    We present the first extraction of the transversity distribution in the framework of collinear factorization based on the global analysis of pion-pair production in deep-inelastic scattering off transversely polarized targets and in proton-proton collisions with one transversely polarized proton. The extraction relies on the knowledge of dihadron fragmentation functions, which are taken from...

  5. 292. Extraction of Transverse Momentum Distributions from semi-inclusive DIS and Drell-Yan data.
    Filippo Delcarro (INFN - National Institute for Nuclear Physics)
    18/04/2018, 10:35
    WG1: Structure Functions and Parton Densities

    We discuss the first attempt at a "global fit" of unpolarized Transverse Momentum Distributions, using data from semi-inclusive deep inelastic scattering and Drell-Yan processes. We describe the main features of this extraction, compare its outcome with new data, and discuss what further developments are needed.
