Scientific paper

We adapt the axioms of the quantum mechanics to the quantum Minkowski space-time coordinates and their transformations under the quantum Lorentz group to show how we can formulate the noncommutative special relativity and its quantum physical observables. we establish in this formalism the quantum analog of the lifetime dilatation formula and the relativistic relations between the energy-momentum four-vector and the mass and the velocity. From the explicit construction of states, we establish the causality principle in the noncommutative special relativity and show that for a free particle moving in the quantum Minkowski space-time, only the length of the velocity and one of its components can be measured exactly and simultaneously. In addition these observables present discret spectrums which imply quantized lifetimes of moving unstable particles.
