  If new TeV scale particles are discovered, it will be important to determine
their width. There is, however, a problematic region, where the width is too
small to be determined directly, and too large to generate a secondary vertex.
For a collection of colored, spin polarized particles, hadronization
depolarizes the particles prior to their decay. The amount of depolarization
can be used to probe the lifetime in the problematic region. In this paper we
apply this method to a realistic scenario of a top-like particle that can be
produced at the LHC. We study how depolarization affects the angular
distributions of the decay products and derive an equation for the
distributions that is sensitive to the lifetime.
