Abstract
We compute the β-function for a massless Yukawa theory in a closed form at the order \( \mathcal{O}\left(1/{N}_f\right) \) in the spirit of the expansion in a large number of flavours Nf . We find an analytic expression with a finite radius of convergence, and the first singularity occurs at the coupling value K = 3.
