Renormalization group flow with unstable particles O.A. Castro-Alvaredo and A. Fring
The renormalization group flow of an integrable two dimensional quantumfield theory which contains unstable particles is investigated. The analysisis carried out for the Virasoro central charge and the conformal dimensionsas a function of the renormalization group flow parameter. This allows toidentify the corresponding conformal field theories together with theiroperator content when the unstable particles vanish from the particlespectrum. The specific model considered is the $SU(3)_{2}$-homogeneousSine-Gordon model.
