Resumen de Application of the SU(1, 1) spinors in the study of the Lorentz transformations (6 pages)

Gerardo Francisco Torres del Castillo

• We show that the orthochronous proper Lorentz transformations that preserve the condition z = 0 can be parametrized by (two-component) SU(1,1) spinors in such a way that the Wigner angle associated with a pair of non-collinear boosts is given by one of the scalar products defined between these spinors.
