Callan-Symanzik equation

From Wikipedia, the free encyclopedia

In physics, the Callan-Symanzik equation is the renormalization relation that tells how the coupling constant changes with momentum in a quantum field theory.

It was discovered independently by Curtis Callan[1] and Kurt Symanzik[2][3] in 1970. Later it is used to understand asymptotic freedom.

It is a special case of a renormalization group equation.
