We present the results for three-loop beta-functions for Yukawa couplings of heavy Standard Model fermions calculated within the unbroken phase of the model.
- The calculation is carried out with the help of the MINCER program in a general linear gauge, and the final result is independent of the gauge-fixing parameters.
- In order to calculate three-point functions, we made use of infrared rearrangement (IRR) trick.
- Due to the chiral structure of the SM a careful treatment of loops with fermions is required to perform the calculation.
