Correction exponents in the Gross - Neveu - Yukawa model at $1/N^2$

Understand

We calculate the critical exponents $\omega_\pm$ in the $d$-dimensional Gross-Neveu model in $1/N$ expansion with $1/N^2$ accuracy.

• These exponents are related to the slopes of the $\beta$-functions at the critical point in the Gross - Neveu - Yukawa model.
• They have been computed recently to four loops accuracy.
• We checked that our results are in complete agreement with the results of the perturbative calculations.
