N2 - We study S-matrices of kinks and breathers of the restricted sine-Gordon theory using the thermodynamic Bethe ansatz method. We found that the underlying conformal field theories at the massless limit are minimal M p q theories, including the non-unitary as well as the unitary ones. This result confirms the identification of the restricted sine-Gordon theory with integrable perturbation of minimal M p q theories.
