# Pauli-Lubanski limit and stress-energy tensor for infinite-spin fields

September 14, 2017

String-localized quantum fields transforming in Wigner's infinite-spin
representations were introduced by Mund, Schroer and Yngvason. We construct
these fields as limits of fields of finite mass $m\to 0$ and finite spin
$s\to\infty$. We determine an infinite-spin quantum stress-energy tensor with a
novel prescription that does not refer to a classical Lagrangean.
