Interference Fragmentation Functions and Valence Quark Spin Distributions in the Nucleon
R. L. Jaffe, Xuemin Jin, Jian Tang
We explore further applications of the twist-two quark interference fragmentation functions introduced earlier. We show that semi-inclusive production of two pions in the current f…
Polarized Lambdas in the Current Fragmentation Region
R. L. Jaffe
Data on the nucleon spin structure suggests that the (and ) quark distributions in the hyperon may be polarized. If this correlation carries over into fragmentation, the…
Spin, Twist and Hadron Structure in Deep Inelastic Processes
Robert L. Jaffe
These notes provide an introduction to polarization effects in deep inelastic processes in QCD. We emphasize recent work on transverse asymmetries, subdominant effects, and the rol…
Novel Quark Fragmentation Functions and the Nucleon's Transversity Distribution
R. L. Jaffe, Xiangdong Ji
We define twist-two and twist-three quark fragmentation functions in Quantum Chromodynamics (QCD) and study their physical implications. Using this formalism we show how the nucleo…
Polarized Fragmentation Functions from
M. Burkardt, R. L. Jaffe
Measurement of the helicity asymmetric cross section for semi-inclusive production of -hyperons in annihilation near the resonance allows a complete determination…
