我们研究了描述D粒子动力学的低能有效理论。这对应于通过将(9+1)维超对称Yang-Mills理论降维到0+1维而得到的量子力学系统，可以解释为Born-Infeld作用量的非相对论极限。我们研究了由两个相同电荷的D粒子组成的系统，并找到了非BPS态的存在的证据，其质量在BPS质量上以λ1/3的方式增长。我们用由两个D粒子拉伸的弦产生的线性势来解释这一现象。文中还对它们与黑洞熵和十一维超引力的可能关系作了一些评论。
We study the low energy effective theory describing the dynamics of D-particles. This corresponds to the quantum-mechanical system obtained by dimensional reduction of (9+1)-dimensional supersymmetric Yang-Mills theory to 0+1 dimensions and can be interpreted as the nonrelativistic limit of the Born-Infeld action. We study the system of two like-charged D-particles and find evidence for the existence of non-BPS states whose mass grows like λ1/3 over the BPS mass. We give a string interpretation of this phenomenon in terms of a linear potential generated by strings stretching from the two D-particles. Some comments on the possible relations to black hole entropy and elevendimensional supergravity are also given.
