关于Liouville理论的S-矩阵

On the S-matrix of Liouville theory

George Jorjadze, Stefan Theisen

摘要:

利用一维场论的关联函数在具有非定域动能和指数势的圆上的循环展开,计算了柱体上Liouville理论的每个手征扇区的S矩阵.这个作用就是半经典散射振幅的生成函数的勒让德变换。它是从渐近内场和外场之间的关系导出的。它的量子散射过程的相关性证明了通过比较明确的循环图计算从这个行动与其他方法计算的S-矩阵,这也是发达国家。

英文摘要:

The S-matrix for each chiral sector of Liouville theory on a cylinder is computed from the loop expansion of correlation functions of a one-dimensional field theory on a circle with a non-local kinetic energy and an exponential potential. This action is the Legendre transform of the generating function of semiclassical scattering amplitudes. It is derived from the relation between asymptotic in- and out-fields. Its relevance for the quantum scattering process is demonstrated by comparing explicit loop diagrams computed from this action with other methods of computing the S-matrix, which are also developed.
