Form factors in the Bullough–Dodd related models: The Ising model
in a magnetic field
O. V. Alekseev L. D. Landau Institute for Theoretical Physics, Russian Academy of Sciences
Abstract:
We consider particular modification of the free-field representation of the form
factors in the Bullough–Dodd model. The two-particles minimal form factors are excluded
from the construction. As a consequence, we obtain convenient representation for the
multi-particle form factors, establish recurrence relations between them and study their
properties. The proposed construction is used to obtain the free-field representation of the
lightest particles form factors in the $\Phi_{1,2}$ perturbed minimal models. As a
significant example we consider the Ising model in a magnetic field. We check that the
results obtained in the framework of the proposed free-field representation are in
agreement with the corresponding results obtained by solving the bootstrap equations.
