Query: Regularity of Bound States   We study regularity of bound states pertaining to embedded eigenvalues of a
self-adjoint operator $H$, with respect to an auxiliary operator $A$ that is
conjugate to $H$ in the sense of Mourre. We work within the framework of
singular Mourre theory which enables us to deal with confined massless
Pauli-Fierz models, our primary example, and many-body AC-Stark Hamiltonians.
In the simpler context of regular Mourre theory our results boils down to an
improvement of results obtained recently in \cite{CGH}.
