Callan–Symanzik equation

In physics, the Callan - Symanzik equation describes how to change the coupling constants with the pulse in a quantum field theory. The equation was set up in each case independently of Curtis Callan and Kurt Symanzik in the 1970s. The equation was of fundamental importance in understanding the asymptotic freedom.

It is a renormalization group equation.
