Lambda Polarization Measured at Hermes and Lambda Spin Structure

Lambda Polarization in Polarized Proton-Proton Collisions at RHIC

We discuss Lambda polarization in semi-inclusive proton-proton collisions, with one of the protons longitudinally polarized. The hyperfine interaction responsible for the ∆-N and Σ-Λ mass splittings gives rise to flavor asymmetric fragmentation functions and to sizable polarized non-strange fragmentation functions. We predict large positive Lambda polarization in polarized proton-proton collisi...

BMN Correspondence at Finite J/N

Employing the string bit formalism of hep-th/0209215, we identify the basis transformation that relates BMN operators in N = 4 gauge theory to string states in the dual string field theory at finite g2 = J 2/N . In this basis, the supercharge truncates at linear order in g2, and the mixing amplitude between 1 and 2-string states precisely matches with the (corrected) answer of hep-th/0206073 fo...

Lambda Polarization in Lepton Induced Reactions

Different phenomenological approaches for Λ and Λ polarization in polarized semi-inclusive deep inelastic scattering and electron-positron annihilation at Z pole are considered. Current and future experiments will soon provide accurate enough data to study spin phenomena in these reactions and distinguish between various models. Talk given at the SPIN-97 VII Workshop on High Energy Spin Physics...

Color Transparency at COMPASS 1 — Feasibility Study —

We examine the potential of the COMPASS experiment at CERN to study color transparency via exclusive vector meson production in hard muon-nucleus scattering. It is demonstrated that COMPASS has high sensitivity to test this important prediction of perturbative QCD. Expanded version of the talk presented at the Workshop on ”Nucleon Structure and Meson Spectroscopy” physics to be studied at the C...
