标题： Soft supersymmetry breaking and finiteness

摘要： 我们计算了一般超对称规范理论中软超对称破缺相互作用的二环$\beta$-函数，强调了在非超对称理论中普遍存在的退化耦合和质量的作用。 我们还表明，一个简单的足够使一环有限的条件可以使理论二环有限，并我们推测了有限的软破缺理论可能的重要性。 显示英文摘要

摘要： We calculate the two-loop $\beta$-functions for soft supersymmetry-breaking interactions in a general supersymmetric gauge theory, emphasising the role of the evanescent couplings and masses that are generic to a non-supersymmetric theory. We also show that a simple set of conditions sufficient for one-loop finiteness renders a theory two-loop finite, and we speculate on the possible significance of finite softly broken theories.
