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…
Nucleon Sigma Term and In-medium Quark Condensate in the Modified Quark-Meson Coupling Model
Xuemin Jin, Manuel Malheiro
We evaluate the nucleon sigma term and in-medium quark condensate in the modified quark-meson coupling model which features a density-dependent bag constant. We obtain a nucleon si…
Interference Fragmentation Functions and the Nucleon's Transversity
R. L. Jaffe, Xuemin Jin, Jian Tang
We introduce twist-two quark interference fragmentation functions in helicity density matrix formalism and study their physical implications. We show how the nucleon's transversity…
New QCD Sum Rules for Nucleon Tensor Charge
Xuemin Jin, Jian Tang
Two new QCD sum rules for nucleon tensor charge are derived from a mixed correlator of spin-1/2 and spin-3/2 nucleon interpolating fields. These sum rules are analyzed along with a…
Chirality and Reliability of Baryon QCD Sum Rules
Xuemin Jin, Jian Tang
The QCD sum-rule method has been widely used in studying various baryon properties. For a given problem, there are usually more than one sum rules and they do not work equally well…
Weak Hyperon Production in ep Scattering
Xuemin Jin, R. L. Jaffe
We study the kinematics and cross section of the scattering process . The cross section is expressed in terms of complex form factors characterizing the hadr…
