Transition magnetic moments between negative parity heavy baryons

Abstract

The transition magnetic moments between negative parity, spin-1/2 heavy baryons are studied in framework of the light cone QCD sum rules. By constructing the sum rules for different Lorentz structures, the unwanted contributions coming from negative (positive) to positive (negative) parity transitions are removed. It is found that the magnetic moments between neutral negative parity heavy ${\Xi }_Q^{\prime 0}$ and ${\Xi }_Q^0$ baryons are very small. Magnetic moments of the ${\Sigma }_Q\to {\Lambda }_Q$ and ${\Xi }_Q^{\prime \pm }\to {\Xi }_Q^{\pm }$ transitions are quite large and can be measured in further experiments.
