黎曼球上玻色子的跃迁振幅和缝合性质

Transition amplitudes and sewing properties for bosons on the Riemann sphere

J. Dimock

摘要:

我们考虑球上的标量量子场,有质量和无质量。在大规模的情况下,我们表明,关联函数定义振幅是一个固定的希尔伯特空间的张量积之间的迹类算子。我们还在这些操作员之间建立了一定的缝纫性能。在无质量的情况下,我们考虑指数场,并有一个共形场论。在这种情况下,振幅只是双线性形式,但我们仍然建立缝合性质。我们的结果是在一个功能积分框架。

英文摘要:

We consider scalar quantum fields on the sphere, both massive and massless. In the massive case we show that the correlation functions define amplitudes which are trace class operators between tensor products of a fixed Hilbert space. We also establish certain sewing properties between these operators. In the massless case we consider exponential fields and have a conformal field theory. In this case the amplitudes are only bilinear forms but still we establish sewing properties. Our results are obtained in a functional integral framework.
