【摘要】We illustrate via the sunset diagram that dimensional regularization \the nonlocal contents of multi-loop disgrams with its equivalence to cutoff regularization scheme recovered only after sub-divergence was subtracted.Then we employed a differential equation approach for calculationg loop diagrams to verify that dimensional regularization deforms the low energy contents before subtraction.The virtues of the differential equation approach are argued especially in nonperturbative perspective. 【总页数】5页(P.317-321)
