Quantum poincaré algebra with standard real structure

A new real quantum Poincaré algebra which is a standard *-Hopf algebra is obtained by the construction of U_q (O(3,2)) (q real). The deformation parameter K is mass-like, and the classical Poincaré algebra is obtained in the limit K → ∞. For our K-Poincaré algebra both Casimirs are given.
