Seeking fixed points in multiple coupling scalar theories in the ε 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, b...
