Scale without Conformal Invariance
Abstract: We investigate the theoretical implications of scale without
conformal invariance in quantum field theory. We argue that the RG flows
of such theories correspond to recurrent behaviors, i.e. limit cycles or
ergodicity. We discuss the implications for the a-theorem and show how
dilatation generators do generate dilatations. Finally, we discuss
well-behaved non-conformal scale-invariant examples.
