Seeking Fixed Points in Multiple Coupling Scalar Theories in the $\varepsilon$ Expansion
Fixed points for scalar theories in 4 − ε, 6 − ε and 3 − ε dimensions are discussed. It is shown how a large range of known fixed points for the four dimensional case can be obtained by using a general framework with two couplings. The original maximal symmetry, O(N), is broken to various subgroups,...
