The Boosts in the Noncommutative Special Relativity
M. Lagraa
Abstract
From the quantum analog of the Iwasawa decomposition of SL(2,C) group and the correspondence between quantum SL(2,C) and Lorentz groups we deduce the different properties of the Hopf algebra representing the boost of particles in noncommutative special relativity. The representation of the boost in the Hilbert space states is investigated and the addition rules of the velocities are established from the coaction. The q-deformed Clebsch-Gordon coefficients descibing the transformed states of the evolution of particles in noncommutative special relativity are introduced and their explicit calculation are given.
