Abstract We derive a new real quantum Poincaré algebra with standard real structure, obtained by contraction of Uq(O(3,2)) (q real), which is a standard real Hopf algebra, depending on a dimension-full parameter κ instead of q. For our real quantum Poincaré algebra both Casimirs are given. The free scalar κ-deformed quantum field theory is considered, it appears that the κ-parameter introduced nonlocal q-times derivatives with ln q~1/κ.
