Reply to the Comment of X. Ji on "Spin and orbital angular momentum in gauge theories" [PRL 100:232002 (2008)]
Xiang-Song Chen, Xiao-Fu Lü, Wei-Min Sun +2
We reply to the Comment of X. Ji [arXiv:0810.4913] on our paper [PRL 100:232002 (2008)], concerning angular momentum algebra, locality, Lorentz covariance, and measurability of our…

Xiang-Song Chen, Xiao-Fu Lü, Wei-Min Sun +2
This is a Reply to the Comment [arXiv:0807.0699] on our paper [PRL 100:232002 (2008)].
Spin and orbital angular momentum in gauge theories: Nucleon spin structure and multipole radiation revisited
Xiang-Song Chen, Xiao-Fu Lü, Wei-Min Sun +2
We address and solve the long-standing gauge-invariance problem of the nucleon spin structure. Explicitly gauge-invariant spin and orbital angular momentum operators of quarks and…
Oscillations in the GSI electron capture experiment
H. Burkhardt, J. Lowe, G. J. Stephenson +2
In a recent paper, oscillations observed in the electron capture probability were attributed to the mixing of neutrino mass eigenstates. This paper is shown to be in error in two r…
Sterile Neutrinos in a 6x6 Matrix Approach
T. Goldman
Quark-lepton symmetry invites consideration of the existence of sterile neutrinos. Long ago, we showed that this approach predicts large neutrino mixing amplitudes. Using a Weyl sp…
Systematic study of pentaquark states: configuration
Jialun Ping, Hongxia Huang, Chengrong Deng +2
Group theoretic method for the systematic study of five-quark states with meson-baryon () configuration is developed. The calculation of matrix elements of many body…
