Query: Front Form Spinors in Weinberg-Soper Formalism and Melosh
  Transformations for any Spin   Using the Weinberg-Soper formalism we construct the front form
$(j,0)\oplus(0,j)$ 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.
