Longitudinal target polarization dependence of Λ̄ polarization and polarized strangeness PDFs

چکیده
According to QED in the hard charged longitudinally polarized lepton–unpolarized quark scattering l + q → l + q lepton transfers its polarization to final quark. Within the simple parton model description of SIDIS the hadron production in the current fragmentation region is described by independent fragmentation of scattered quark. Then the (anti)quark polarization can be transferred to produced Λ̄. For unpolarized target the final quark polarization, Pq′ , is related to the beam polarization, PB, by

Longitudinal Polarization of Λ and Λ̄ in Deep - Inelastic Scattering at Compass
Production of Λ and ¯ Λ hyperons in deep-inelastic scattering of 160 GeV/c polarized muons is under study in the COMPASS (CERN NA58) experiment. Preliminary results on longitudinal polarization of Λ and ¯ Λ hyperons from the data collected during the 2002 run are presented. The study of longitudinal polarization of Λ(¯ Λ) hyperons in the deep-inelastic scattering (DIS) can provide information o...
متن کاملLongitudinal Polarization of Λ and Λ̄ Hyperons in Lepton-Nucleon Deep-Inelastic Scattering
We consider models for the spin transfer to Λ and Λ̄ hyperons produced in lepton-nucleon deep-inelastic scattering. We make predictions for longitudinal Λ and Λ̄ spin transfer for the COMPASS experiment and for HERA, and for the spin transfer to Λ hyperons produced at JLAB. We show that a measurement of Λ polarization in the COMPASS experiment in a region of x that has not previously been explore...

متن کاملIntrinsic Polarized Strangeness and Λ Polarization in Deep-Inelastic Production
We propose a model for the longitudinal polarization of Λ baryons produced in deep-inelastic lepton scattering at any xF , based on static SU(6) quark-diquark wave functions and polarized intrinsic strangeness in the nucleon associated with individual valence quarks. Free parameters of the model are fixed by fitting NOMAD data on the longitudinal polarization of Λ hyperons in neutrino collision...

Preliminary results for the longitudinal polarization of Λ and ¯ Λ hyperons in longitudinally polarized proton-proton collisions at √ s = 200 GeV are presented. The Λ(¯ Λ) candidates are reconstructed at mid-rapidity (|η| < 1) with the time projection chamber of the STAR experiment at RHIC, using 0.5 pb −1 collected in 2003 and 2004 with beam polarizations of up to 45%. Their mean longitudinal ...
