  We discuss conformal invariance of the massless Thirring model. We show that
conformal symmetry of the massless Thirring model is dynamically broken due to
the constant of motion caused by the equations of motion. This confirms the
existence of the chirally broken phase in the massless Thirring model (Eur.
Phys. J. C20, 723 (2001), which is accompanied by the appearance of massless
(pseudo)scalar Goldstone bosons (Eur. Phys. J. C24, 653 (2002), hep-th/0210104
and hep-th/0305174).
