Abstract
We introduce an on shell renormalization scheme in which the mass parameter of the minimal subtraction (MS) scheme is replaced with the pole mass obtained from the loop-order expansion of the pole mass in the MS scheme. As a consequence, the quartic coupling constant remains the same as that of the MS scheme, and the vacuum expectation value gets contributions from the one-particle-irreducible diagrams. We also show the renormalization group invariance of the pole mass in this scheme.
