摘要

在这篇贡献中，我们报告了手性Ising，手性XY和手性Heisenberg Gross-Neveu-Yukawa模型在四个环的$D=4$维周围的$\beta$ -函数和异常维的摄动测定，以及在非平凡，红外稳定不动点的临界指数的第一次pad外推到$D=3$这个数量级。本演讲基于Ref. \cite{Zerf:2017zqi}。

Gross-Neveu-Yukawa Models at Four Loops

In this contribution we report on the perturbative determination of $\beta$-functions and anomalous dimensions for the chiral Ising, chiral XY and chiral Heisenberg Gross-Neveu-Yukawa model around $D=4$ dimensions at four loops and the first Pad\'e extrapolation of critical exponents at non-trivial, infrared stable fixed points to $D=3$ to this order. This talk is based on Ref.~\cite{Zerf:2017zqi}.
