在矩阵理论中,引力子-引力子散射的有效作用是相对速度的双重展开和逆分离。我们讨论了这种展开式的系统论,并对主题矩阵理论进行了新的检验。低能超引力预测了v{sup 6}/r{sup 14}项的系数,这是一种双圈效应,与显式矩阵模型计算一致。{版权所有}{ITAL 1997}{ITAL The American Physitive Society}
In matrix theory the effective action for graviton-graviton scattering is a double expansion in the relative velocity and inverse separation. We discuss the systematics of this expansion and subject matrix theory to a new test. Low-energy supergravity predicts the coefficient of the v{sup 6}/r{sup 14} term, a two-loop effect, in agreement with explicit matrix model calculations. {copyright} {ital 1997} {ital The American Physical Society}
