Massive Integrable Soliton Theories
Timothy J. Hollowood, J. Luis Miramontes, Q-Han Park
Massive integrable field theories in dimensions are defined at the Lagrangian level, whose classical equations of motion are related to the ``non-abelian'' Toda field equatio…
Quantum scattering of charged solitons in the complex sine-Gordon model
Nicholas Dorey, Timothy J. Hollwood
The scattering of charged solitons in the complex sine-Gordon field theory is investigated. An exact factorizable S-matrix for the theory is proposed when the renormalized coupling…
The Exact Mass-Gap of the Supersymmetric O(N) Sigma Model
Jonathan M. Evans, Timothy J. Hollowood
A formula for the mass-gap of the supersymmetric O() sigma model () in two dimensions is derived: , where and i…
Integrable theories that are asymptotically CFT
Jonathan M. Evans, Timothy J. Hollowood
A series of sigma models with torsion are analysed which generate their mass dynamically but whose ultra-violet fixed points are non-trivial conformal field theories -- in fact SU(…
