Anomalous magnetic and electric moments of and lepton flavor mixing matrix in effective lagrangian approach
J. Q. Zhang, X. C. Song, W. J. Huo +1
In an effective lagrangian approach [EM97] to new physics, the authors in ref. [HL99] pushed tau anomalous magnetic and electric dipole moments (AMDM and EDM) down to an…
Tests of SU(3) Symmetry-Breaking for Baryonic Beta Transitions in the Standard Model
P. K. Kabir, X. Song
It is generally assumed that deviations from flavor SU(3) symmetry arise entirely from quark mass-differences, reflected in the mass splittings between strange and nonstrange membe…
Intrinsic Charm in the Nucleon
X. Song
The quark spin and flavor structure of the nucleon is discussed in the SU(4) symmetry breaking chiral quark model. The spin and flavor contents for charm quarks and anti-charm quar…
Quark Spin and Orbital Angular Momentum in the Baryon
X. Song
The spin and orbital angular momentum carried by different quark flavors in the nucleon are calculated in the SU(3) chiral quark model with symmetry-breaking. The model is extended…
Quark Spin and Orbital Angular Momentum in the Chiral Quark Model
X. Song
Quark spin and orbital angular momentum in the nucleon are calculated in symmetry-breaking chiral quark model. The results are compared with data and other models.
Quark Orbital Motion in the Nucleon
X. Song
An unified scheme for describing both spin and orbital motion in symmetry-breaking chiral quark model is suggested. The analytic results of the spin and orbital angular momenta car…
