Modified Born-Jordan Method For Constructing The Commutation Relation Of Coordinate and Momentum

The Born-Jordan method for constructing the quantum condition of the Matrix Mechanics is pointed out to be inappropriate in the present work. We modify this method and reconstruct the quantum condition by setting up a new expression for the Bohr quantum condition with the help of the (n,n) elements of the matrix $\oint\hat{p}(t){\rm d}\hat{x}(t)$.

The Sigma_c and Lamda_c magnetic moments from QCD spectral sum rules

We use QCD spectral sum rules to extract the Sigma_c and Lambda_c magnetic moments. The elctromagnetic field is treated as the external field. We adopt the value of the susceptibility chi=-4.5 GeV^{-2}, which is determined from an overall analysis of the octet baryon magnetic moments. Our result for Sigma_c is in agreement with the quark model prediction, while slight deviation exists from the Lambda_c.
