Decrypting gauge-Yukawa cookbooks

Understand

For many years, theorists have calculated formulas for useful quantities in general gauge-Yukawa theories.

• However, these cookbooks are often very difficult to use since the general notation is far removed from practical model building.
• In this paper, we present the structure delta which allows us to use a surprisingly convenient notation that bridges the gap between general gauge-Yukawa theories and specific models.
• This is particularly useful for the computation of beta functions, but can also be extended to handle spontaneous symmetry breaking, the effective potential and a variety of other quantities.
