What this part means
The expressions on both sides represent the same quantity under the stated assumptions.
Its job in the formula
The equals sign connects the complete expression on the left with the complete expression on the right. Both sides must have compatible units.

The passage around this formula
If the vacuum has a history of discrete jumps, a natural follow-up question is whether it also has a history of gradual drift — whether the constants fixed by electroweak symmetry breaking are quietly creeping away from their frozen values even now. This is a genuinely different physical question from phase transitions, and the Standard Model already contains a mild, well-understood version of scale dependence that should not be confused with time variation: coupling constants “run,” meaning their effective strength depends on the energy scale Q at which they are probed, governed by renormalization-group equations of the schematic form . where the are calculable…
