论文摘要
我们在存在附加边界耦合的情况下对开放字符串路径积分的可能定义发表了一些评论，该耦合对应于字符串末端的质量。这些耦合并不是共同不变的，这意味着在非临界弦乐案例中，一个耦合是在边界的1D度量或重新构度上集成。我们在存在附加恒定量规背景的情况下计算圆盘上的分区函数，并评论相应散射幅度的结构。
We make some remarks on possible definition of open string path integral in the presence of additional boundary couplings corresponding to the presence of masses at the ends of the string. These couplings are not conformally invariant implying that as in a non-critical string case one is to integrate over the 1d metric or reparametrizations of the boundary. We compute the partition function on the disc in the presence of an additional constant gauge field background and comment on the structure of the corresponding scattering amplitudes.
