Query: Bethe state norms for the Heisenberg spin chain in the scaling limit   In this paper we discuss the norms of the Bethe states for the spin one-half
Heisenberg chain in the critical regime. Our analysis is based on the ODE/IQFT
correspondence. Together with numerical work, this has lead us to formulate a
set of conjectures concerning the scaling behavior of the norms. Also, we
clarify the role of the different Hermitian structures associated with the
integrable structure studied in the series of works of Bazhanov, Lukyanov and
Zamolodchikov in the mid nineties.
