Abstract
In this contribution we report on the perturbative determination of -functions and anomalous dimensions for the chiral Ising, chiral XY and chiral Heisenberg Gross-Neveu-Yukawa model around dimensions at four loops and the first Pad\'e extrapolation of critical exponents at non-trivial, infrared stable fixed points to to this order. This talk is based on Ref. [Zerf:2017zqi].
