  1. 125. TMDs and spin asymmetries in SIDIS
    Harut Avagyan (Jefferson Lab)
    12/12/2017, 09:00
    In recent years the measurements of single spin asymmetries (SSAs) in final state hadronic distributions in semi-inclusive processes have been widely used to access the underlying Transverse Momentum Dependent (TMD) parton distributions. The detailed understanding of the orbital structure of partonic distributions, encoded in TMD PDFs has been widely recognized as one of the key objectives of...

  2. 94. First extraction of transversity from a global fit
    Marco Radici (INFN Pavia)
    12/12/2017, 09:40
    We present the first extraction of the transversity distribution in the frame- work of collinear factorization based on the global analysis of pion–pair pro- duction in deep–inelastic scattering off transversely polarized targets and in proton–proton collisions with one transversely polarized proton. The extrac- tion relies on the knowledge of dihadron fragmentation functions, which are taken...

  3. 81. Recent analysis of Drell-Yan data
    Ignazio Scimemi (Universidad Complutense de Madrid)
    12/12/2017, 10:05
    We present a comprehensive analysis and extraction of the unpolarized transverse momentum dependent (TMD) parton distribution functions, which are fundamental constituents of the TMD factorization theorem. We provide a general review of the theory of TMD distributions, and present a new scheme of scale fixation. This scheme, called the ζ-prescription, allows to minimize the impact of...
