Bounds on multiscalar CFTs in the ε expansion
Abstract We study fixed points with N scalar fields in 4 − ε dimensions to leading order in ε using a bottom-up approach. We do so by analyzing O(N) invariants of the quartic coupling λ ijkl that describes such CFTs. In particular, we show that λ iijj and λ ijkl 2 $$ {\lambda}_{ijkl}^2 $$ are restri...
