我们从11维超引力和矩阵理论的两侧详细分析了D粒子的三体相互作用。在超引力条件下，我们推导了包含二体和三体相互作用项的D粒子经典玻色子有效作用量的完整表达式。在矩阵理论中，我们在双圈近似下计算了单粒子对象素相移的不可约贡献。结果与超引力的预言完全一致，从而为矩阵理论猜想的离散光锥解释提供了有力的支持，使之可能成为M理论的一个非微扰定义。
We present detailed analyses of the 3-body interactions of D-particles from both sides of 11-dimensional supergravity and Matrix theory. In supergravity, we derive a complete expression for the classical bosonic effective action for D-particles including 2-and 3-body interaction terms. In Matrix theory, we compute 1-particle irreducible contributions to the eikonal phase shift in the two-loop approximation. The results precisely agree with the predictions from supergravity and thus provide a strong support to the discrete light-cone interpretation of the Matrix-theory conjecture as a possible non-perturbative definition of M-theory.
