Hyperon Decays and Partial Conservation of Tensor Current
Abstract
On the basis of the partial conservation of tensor current (PCTC) hypothesis, sum rules for the magnetic moments of baryons are obtained, one of which yields μ^{}_{Ξ}=1.4+/1.5 nm. The ratio of Dtype coupling to Ftype coupling DF is obtained from the magneticmoment relations in broken unitary symmetry in SU(3) and SU(6). Sum rules for the transition magnetic moments μ_{BA} of A>B+e^{}+ν̄ are obtained as a consequence of PCTC. The contribution of the magnetic term to the various semileptonic decay rates of hyperons is estimated on the basis of SU(3) and found to be less than 8% of that of the charge term for the vector current.
