INTEGRABLE SIGMA MODELS

International Journal of Modern Physics A, 1991
Integrability of sigma models is investigated in arbitrary dimensions. The conditions of the integrability are found and the corresponding linear eigenvalue equations are given. Some new classes of classically integrable sigma models are found in two and higher dimensions containing all the known models.

Beyond the Sigma-Model

2016
In the previous chapter we restricted our attention to a specific class of new physics effects, that we can classify as “non-linear \(\sigma\)-model effects”. These are modifications of the SM driven by the pNGB nature of the Higgs and the associated non-linear \(\sigma\)-model structure of the effective Lagrangian.

Geometric \(\sigma\)-models

1998
Summary: A class of nonlinear \(\sigma\)-models coupled to gravity is defined by identifying the coordinates of spacetime with the components of a set of scalar fields. The obtained theories have purely geometric character and necessarily possess soliton solutions with topologically nontrivial scalar sectors.
