A novel algebraic criterion for the Bisognano-Wichmann property of one-particle nets was  recently found by V. Morinelli. In this talk I will explain how to apply this criterion to the  case of massless, integer spin particles using the Mackey subgroup theorem. In the next  step the result will be lifted from the one-particle nets to Haag-Kastler nets using the  assumption of asymptotic completeness. The argument relies on scattering theory of  massless particles due to Buchholz and its recent simplifications. Also ideas from the  massive case, which had been solved by J. Mund, enter into the discussion. The talk is based  on a joint paper with V. Morinelli.

This talk is part of series of talks affiliated with the virtual Mittag-Leffler workshop "Scattering, microlocal analysis and renormalization", organized by Claudio Dappiaggi, Jacob Schach Møller and Michal Wrochna. The full schedule can be found at:
