Gluon polarization in Nucleon is evaluated in the valon representation of hadrons. It is shown that although δg/g is small at the currently measured kinematics, it does not imply that the gluon contribution to the nucleon spin is small. In fact...

We derive the Leading-Order (LO) master equation

to extract the polarized gluon distribution G(x,Q2) =xδg(x,Q2) from polarized proton structure function,

gp1 (x,Q2). By using a Laplace-transform technique, ...

The spin dependent structure function, gww2 , is calculated in the valon model. A simple approach is given for the determination of the twist-3 part of g¯2(x,Q2) inMellin space, thus enabling us to obtain the full transverse structure function g2(x...

and low spin states. Natural bond orbital and quantum

theory of atoms in molecules analyses was carried out with B3LYP/6-311G(d,p) to understand

the nature of complex bond character and electronic transition in complexes. Electrostatic...

Ji\\'s decomposition of nucleon spin is used and the orbital angular momentum of quarks and gluon are calculated. We have utilized the so called valon model description of the nucleon in the next to leading order. It is found that the average...

We have utilized the concept of valon model to calculate the spin structure functions of proton, eutron, and deuteron. The valon structure itself is universal and arises from the perturbative dressing of the valence quark in QCD. Our results agree...

Within the framework of the so-called valon model, we argue that a substantial part of the nucleon spin,

about 40%, is carried by the polarized valence quarks. The remaining is the result of cancelations between gluon polarization...

A next-to-leading order QCD calculation of non-singlet spin structure function, g1NS is presented within the valon representation of hadrons. In the valon model, it is assumed that a nucleon is composed of three dressed valence quarks: the valons...
