  We consider a generalized Lieb-Liniger model, describing a one-dimensional
Bose gas with all its conservation laws appearing in the density matrix. This
will be the case for the generalized Gibbs ensemble, or when the conserved
charges are added to the Hamiltonian. The finite-size corrections are
calculated for the energy spectrum. Large-distance asymptotics of correlation
functions are then determined using methods from conformal field theory.
