  1. 84. W and Z production at the LHC
    Pasquale Di Nezza (INFN LNF)
    14/12/2017, 11:00
    At energy scales typical for electroweak boson production, LHC measurements can provide not only important tests of the Standard Model, but also allow the partonic content of the proton to be constrained by fundamental inputs to parton distribution functions (PDFs). In particular, results from LHCb, a single-arm forward spectrometer instrumented in the pseudorapidity region 2 < η < 5 and...

  2. 92. 3D structure of the proton from double parton distribution functions
    Matteo Rinaldi (Universitat de València, Institut de Fisica Corpuscular and CSIC, Valencia, Spain)
    14/12/2017, 11:25
    Double parton distribution functions (dPDFs), accessible in high energy proton-proton and proton nucleus collisions, in double parton scattering processes (DPS), represent a new and promising complementary tool, w.r.t. TMDs and GPDs, to explore the 3D partonic structure of the proton. In particular, they encode unknown information on how two partons are correlated in hadrons. To...

  3. 107. Higher twists and Lambda polarization
    Marc Schlegel (University of Tuebingen)
    14/12/2017, 11:50
    The (transverse) polarization of Lambda baryons measured in hard reactions may be described in perturbative QCD in terms of polarized twist-3 fragmentation functions. A particularly simple reaction is the production of Lambdas in electron-positron annihilation. Certain aspects of an NLO calculation for transverse spin observables in this process are discussed in this talk.

  4. 120. Transverse Momentum Effects in e+e− inclusive single-hadron production
    Jose Osvaldo Gonzalez Hernandez (INFN Turin)
    14/12/2017, 12:15
    Transverse momentum dependent fragmentation functions (TMD FFs) contain essential information about hadronization. The non-perturbative ingredients of TMD FFs, should be inferred from phenomenological anal- yses of SIDIS and e+e− annihilation data. For this purpose, it is fun- damental to have at our disposal measurements that allow to decouple different regimes of physics and the effects...

  5. 80. Transverse momentum distributions of hadrons within jets
    Cristian Pisano (INFN Pavia)
    14/12/2017, 12:40
    By adopting a generalised parton model approach at leading order in QCD, including spin and intrinsic parton motion effects, we study the Collins azimuthal asymmetries for pions within a large-pT jet produced at mid-rapidity in polarised hadronic collisions. Using available information on the quark transversity distributions and the pion Collins functions, as extracted from semi-inclusive,...
