A quantum field theory with nonquadratic couplings, requiring perturbative, lattice, bootstrap, algebraic, or other nonperturbative methods.

This is an authored directed relation from the source endpoint to the target endpoint.
Coupling constants multiply or normalize interaction operators and set perturbative expansion parameters in an interacting QFT.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Interacting QFTs include nonquadratic couplings.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.
