Bicrossproduct structure of the null-plane quantum Poincare algebra
Oscar Arratia, Francisco J. Herranz, Mariano A. del Olmo
Abstract
A nonlinear change of basis allows to show that the non-standard quantum deformation of the (3+1) Poincare algebra has a bicrossproduct structure. Quantum universal R-matrix, Pauli-Lubanski and mass operators are presented in the new basis.
