Susanna Horn,Angelina Korsunovaed. Special attention is paid to various divergences of Feynman integrals because their interplay is a characteristic feature of explicit prescriptions for asymptotic expansions in momenta and masses. A brief review of methods for analytic evaluation of Feynman integrals is presented. In addition to作者: Heart-Rate 時(shí)間: 2025-3-22 23:27 作者: 壓倒 時(shí)間: 2025-3-23 03:12
