The four-loop $β$ -function from vacuum supergraphs and the NSVZ relation for $N = 1$ SQED regularized by higher derivatives

Ilya Shirokov, Valentina Shirokova

In $N = 1$ SQED with $N_{f}$ flavors regularized by higher derivatives we obtain the four-loop beta function using a method based on calculating vacuum supergraphs. For this pur…
