Query: Asymptotic completeness for the massless spin-boson model   We consider generalized versions of the massless spin-boson model. Building
on the recent work in 'Approach to ground state and time-independent photon
bound for massless spin-boson models' (arXiv:1109.5582, Annales H. Poincare,
2012) and 'Propagation bounds and soft photon bounds for the massless
spin-boson model' (submitted to arXiv jointly with the present paper), we prove
asymptotic completeness.
