Bubble-resummation and critical-point methods for $$\beta $$ β -functions at large N
Abstract We investigate the connection between the bubble-resummation and critical-point methods for computing the $$\beta $$ β -functions in the limit of large number of flavours, N, and show that these can provide complementary information. While the methods are equivalent for single-coupling theo...
