英文摘要We perform an analysis of the quark angular momentum in a light-cone representation by taking into account the effect due to the Melosh-Wigner rotation and find that there is a relativistic correction factor connecting the quark orbital angular momentum with the quark model spin distribution: L-q(x) = [M-L(x)]Delta q(QM)(x). The quark orbital angular momentum L-q(x) and the quark helicity distribution L-q(x) are connected to the quark model spin distribution Delta q(QM)(x) by a relation 1/2 Delta q(x) + L-q(x) = 1/2 Delta q(QM)(x), which means that one can decompose the quark model spin contribution Delta q(QM)(x) by a quark helicity term Delta q(x) plus an orbital angular momentum term L-q(x). There is also a new relation connecting the quark orbital angular momentum with the measurable quark helicity distribution and transversity distribution (delta q(x)): Delta q(x) + L-q(x) = delta q(x), from which we may have new sum rules connecting the quark orbital angular momentum with the nucleon axial and tensor charges.
