| contents | We consider the XXZ spin chain in the scaling limit in the Matsubara direction. The main result of this paper is new representations for the functions $Ψ(l, κ)$ and $Θ(l, m; κ, α)$ associated with the function $ω(ζ, ξ; κ, κ)$ found in the expression for the correlation function of the generators of the fermionic basis for the XXZ spin chain. The final result incorporates the case of particle-hole excitations which is needed for the relation of the fermionic basis to the Virasoro basis of the CFT descendants. |
