Abstract

The braid group representation associated with the 10-dimensional representation of SU(4) is derived, based on the weight conservation and extended Kauffman diagrammatic technique. The corresponding trigonometric and rational solutions of the quantum Yang-Baxter equations are constructed in terms of the Yang-Baxterization procedure.
