Abstract:
Using the Weinberg-Soper formalism we construct the front form (j,0)(0,j)(j,0)\oplus(0,j) spinors. Explicit expressions for the generalised Melosh transformations up to spin two are obtained. The formalism, without explicitly invoking any wave equations, reproduces spin one half front-form results of Melosh, Lepage and Brodsky, and Dziembowski.
