  1. 24. Sivers program at STAR
    Dr Salvatore Fazio (Brookhaven National Laboratory)
    2/3/17, 2:00 PM
    Accessing the Sivers TMD function in proton+proton collisions through the measurement of transverse single spin asymmetries (TSSAs) in weak boson production is an effective path to test the fundamental QCD prediction of the non-universality of the Sivers function. Furthermore, it provides data to study the spin-flavor structure of valence and sea quarks inside the proton and to test the...

  2. 84. Perturbative vs non-perturbative aspects of TMD phenomenology
    Prof. Mariaelena Boglione (University of Turin and INFN Torino)
    2/3/17, 2:25 PM
    The practical implementation of TMD phenomenology becomes particularly involved when it comes to describing SIDIS cross sections over a wide range of transverse momenta. Even more so in the region of low to moderate $q_T$, where the interplay between perturbative and non-perturbative effects are more prominent. I will discuss a (personal) selection of relevant issues and show their...

  3. 77. Probing collinear and TMD fragmentation functions through hadron distribution inside the jet
    Prof. Zhongbo Kang (UCLA)
    2/3/17, 2:50 PM
    We consider both the collinear and transverse momentum distribution of hadrons within a fully reconstructed jet. In particular, we demonstrate how such a distribution can be used to probe collinear and TMD fragmentation functions. We show the phenomenological application, for both unpolarized and polarized collisions (e.g., Collins azimuthal asymmetry), which has been measured at both RHIC and/or LHC.

  4. 61. Study of Unpolarized TMD Functions from HERMES Data
    Mr Mason Albright (Pennsylvania State University)
    2/3/17, 3:15 PM
    We study unpolarized TMD distributions and fragmentation functions using HERMES data. We perform both Hessian and Monte Carlo analyses of the data and extract the widths of unpolarized TMDs. Critical evaluation of flavor dependence of widths is reported.
