abstract
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.

Transverse distributions of the energy-momentum tensor for a spin-$3/2$ baryon
The paper derives the longitudinal-boost dependence of transverse energy-momentum tensor distributions for a spin-3/2 baryon and matches the infinite-momentum limit to direct light-front results.
