Book excerpt: We have performed a measurement of transverse polarization for A baryons produced after the collision of longitudinally polarized electrons and unpolarized positrons at the Z0 resonance. The measurement is based on 560,000 Z0 decays produced at the SLC and collected by the SLD collaboration at SLAC between 1993 and 1998. We define the axis of polarization as the cross product of the thrust axis direction and the [Lambda] momentum and we use the longitudinal polarization of the incoming electrons to sign the thrust axis according to the direction of the color field, thereby testing the Andersson-Gustavson-Ingelman model for [Lambda] transverse polarization. We find that if the mechanism responsible for [Lambda] transverse polarization is completely correlated with the color field direction -0.22% (P[Lambda])[perpendicular]

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We measure the transverse polarization of ? and ???????? hyperons produced in proton-proton collisions at a center-of mass energy of 7 TeV is measured. The analysis uses 760 ?b−1 of minimum bias data collected by the ATLAS detector at the LHC in the year 2010. The measured transverse polarization averaged over Feynman xF from 5 × 10−5 to 0.01 and transverse momentum pT from 0.8 to 15 GeV is −0.010 ± 0.005(stat) ± 0.004(syst) for ? and 0.002 ± 0.006(stat) ± 0.004(syst) for ???????? . It is also measured as a function of xF and pT, but we observed no significant dependence on these variables. Prior to this measurement, the polarization was measured at fixed-target experiments with center-of-mass energies up to about 40 GeV. The ATLAS results are compatible with the extrapolation of a fit from previous measurements to the xF range covered by this measurement.

Available in PDF, EPUB and Kindle. Book excerpt: Recent measurements using the CLAS detector at Jefferson Lab of the reactions {gamma} + p {yields} K{sup +} + {Lambda} and {gamma} + p {yields} K{sup +} + {Sigma}{sup 0} have been used to extract the spin transfer coefficients C{sub x} and C{sub z} for the first time. These observables quantify the degree of the photon circular polarization that is transferred to the recoiling hyperons in the scattering plane. The unexpected result is that {Lambda} hyperons are produced '100% polarized' as seen when combining C{sub x} and C{sub z} with the induced transverse polarization, P. Furthermore, C{sub x} and C{sub z} seem to be linearly related. This paper discusses the experimental results and offers a hypothesis which can explain these observations. We show how the produced strange quark can be subject to a pure spin-orbit type of interaction which preserves its state of polarization throughout the hadronization process.
