  2. 14. Asymmetry measurements in e+e-: methods, open points and perspectives

    some points which I think wold be valuable to discuss -The correct frame to extract azimuthal correlations in e+e-: The theory is mostly worked out for back-to-back hadrons. However, for experimental and theoretical reasons, two other methods are used: The 'thrust' method and lately modulations in jets. What are the consequences for fits? E.g. are evolution effects different for...

  3. 6. Collins asymmetries in e+e- annihilation
    Isabella Garzia (INFN)
    03/09/2015, 16:30
    Inclusive hadron production cross section and angular distributions in $e^+e^-$ collisions shed light on fundamental questions of hadronization and fragmentation processes. We present measurements of the so called Collins azimuthal asymmetries in inclusive production of hadron pairs in $e^+e^- \rightarrow h_1h_2X$ annihilation process, where the two hadrons are produced in opposite...

  4. 16. Interplay between the Collins and the di-hadron asymmetries
    Franco Bradamante (Universita e INFN, Trieste (IT))
    03/09/2015, 17:05
    The recent COMPASS results on the interplay between the Collins asymmetry and the di-hadron asymmetry are briefly presented. Their possible implications on the transversity extraction are discussed. The feasibility of the same studies in e+e- annihilation should also be addressed during the round tables.

  5. 17. Dependence of 2h SIDIS structure functions on DeltaPhi
    Aram Kotzinian (ANSL (Yerevan Physics Institute) (AM))
    03/09/2015, 17:40
    The general formalism to study the dependence of 2h SIDIS structure functions on DeltaPhi. Examples: 1) Sivers effect in 2h production in CFR. a) General formula and convolution expressions for SFs b) Results based on mLEPTO and comparison with released COMPASS data 2) A_LU^sin(DeltaPhi) asymmetry in b2b SIDIS (one hadron produced in the CFR and the second -- in the TFR). Leading...

  6. 13. Transverse Spin Effects in Two Hadron Electroproduction
    Hrayr Matevosyan (University of Adelaide)
    03/09/2015, 18:15
    The measurement of various angular single spin asymmetries (SSA) in a single hadron production off a transversely polarized target in semi-inclusive deep inelastic scattering (SIDIS) process allows to access both the Sivers and Collins effects describing the correlations of the the transverse spin and transverse momenta in both parton distribution and fragmentation functions. In our recent...
