标题： Gravitational Collapse and Calogero Model

摘要： 我们研究从描述无质量标量场球对称引力坍缩的约化Wheeler-DeWitt波函数得到的S矩阵的解析结构。 S矩阵中的简单极点出现在欧几里得时空中，欧几里得Wheeler-DeWitt方程是Calogero模型的一种变体，这与共形力学和量子瞬子有关。 显示英文摘要

摘要： We study the analytic structure of the S-matrix which is obtained from the reduced Wheeler-DeWitt wave function describing spherically symmetric gravitational collapse of massless scalar fields. The simple poles in the S-matrix occur in the Euclidean spacetime, and the Euclidean Wheeler-DeWitt equation is a variant of the Calogero models, which is discussed in connection with conformal mechanics and a quantum instanton.
