We generalize Emery and Kivelson's (EK) bosonization-refermionizationtreatment of the 2-channel Kondo model to finite system size and on the EK-lineanalytically construct its exact eigenstates and finite-size spectrum. Thelatter crosses over to conformal field theory's (CFT) universalnon-Fermi-liquid spectrum (and yields the most-relevant operators' dimensions),and further to a Fermi-liquid spectrum in a finite magnetic field. Our approachelucidates the relation between bosonization, scaling techniques, the numericalrenormalization group (NRG) and CFT. All CFT's Green's functions are recoveredwith remarkable ease from the model's scattering states.Comment: 4 pages, 1 figure, Revte
