The Gluon Spin in the Chiral Bag Model

We study the gluon polarization contribution at the quark model renormalization scale to the proton spin, Γ, in the chiral bag model. It is evaluated by taking the expectation value of the forward matrix element of a local gluon operator in the axial gauge A = 0. It is shown that the confining boundary condition for the color electric field plays an important role. When a solution satisfying th...

The Proton Spin Problem in the Chiral Bag Model

The flavor singlet axial charge has been a source of study in the last years due to its relation to the so called Proton Spin Problem. The relevant flavor singlet axial current is anomalous, i.e., its divergence contains a piece which is the celebrated UA(1) anomaly. This anomaly is intimately associated with the η ′ meson, which gets its mass from it. When the gauge degrees of freedom of QCD a...

Chapter VII Language - Action Perspective ( LAP )

The Language-action perspective (LAP) provides an alternative foundation for analyzing and designing effective information systems. The fundamental principle of the LAP approach is people perform actions through communication; therefore, the role of information systems is to support such communications among people to achieve business goals. Basing on linguistic and communicative theories, the ...
