The BulloughâDodd model is an integrable model in 1+1-dimensional quantum field theory introduced by Robin Bullough and Roger Dodd. Its Lagrangian density is
where is a mass parameter, is the coupling constant and is a real scalar field.
The BulloughâDodd model belongs to the class of affine Toda field theories.
The spectrum of the model consists of a single massive particle.
