These flows include in particular the flow between the Tricritical Ising model and the Ising model. Form factors of the trace operator with an arbitrary number of particles are constructed, and numerical checks on the central charge are performed with four particles contribution. Large discrepancies with respect to the exact results are observed in most cases.", "revisions": [ { "version": "v2", "updated": "2005-02-22T13:26:49.000Z" } ], "analyses": { "subjects": [ "11.10.-z", "11.55.Ds", "11.10.Kk" ], "keywords": [ "form factors", "massless coset models", "trace operator", "minimal model", "arbitrary number" ], "tags": [ "journal article" ], "publication": { "publisher": "Elsevier", "journal": "Nucl.
