Regularizing the quark-level linear sigma-model

摘要

We show that the finite difference, -i pi(2)m(2), between quadratic and logarithmic divergent integrals integral d(4)p[m(2)(p(2) - m(2))(-2) - (p(2) - m(2))(-1)], as encountered in the linear sigma-model, is in fact regularization independent. [References: 10]
