  1. 31. Phenomenological constraints on transverse single-spin asymmetries from Lorentz invariance relations
    Daniel Pitonyak (Penn State Berks)
    2/3/17, 9:00 AM
    We review the status of transverse single-spin asymmetries (SSAs) A_N in proton-proton collisions within the collinear twist-3 framework. We use newly derived constraints from Lorentz invariance relations, along with previously known equation of motion relations, to rewrite A_N in terms of a maximum number of so-called kinematical functions, which are weighted integrals of TMD functions. ...

  2. 16. Scale evolution equations for transverse momentum weighted TMD functions.
    Dr Shinsuke Yoshida (Los Alamos)
    2/3/17, 9:25 AM
    We discuss the next-leading-order(NLO) transverse-momentum weighted single-transverse spin asymmetry in semi inclusive deep inelastic scattering based on the collinear factorization approach. The leading-order cross section can be expressed in terms of twist-3 functions associated with transverse momentum weighted TMD functions and therefore the NLO contribution provides scale evolution...

  3. 52. Parton Orbital Angular Momentum: Experimental Leads
    Prof. Simonetta Liuti (University of Virginia)
    2/3/17, 9:50 AM
    We will present and discuss how parton orbital angular momentum can be accessed by measuring the correlation of the parton intrinsic transverse momentum and the proton momentum transfer encoded in both twist three Generalized Parton Distributions (GPDs) and in matrix elements that depend on the parton transverse momentum (Generalized TMDs).

  4. 92. Universal Transverse Momentum Dependent Fragmentation in Jets
    Dr Duff Neill (LANL)
    2/3/17, 10:15 AM
    Fragmentation is a fundamental probe of the transition between the perturbative description of QCD and the non-perturbative regime. One would like to understand how the partonic quantum numbers, flavor, spin, charge, and momentum, are transported to the hadronic final state. Of utmost importance is simply the conversion of the momentum of a parton into the momentum carried by the observed...
