旋转管柱生产截面

Production cross section of rotating string

Tsunehide Kuroki, Toshihiro Matsuo

摘要:

在玻色弦论中,我们计算了两个光态碰撞产生单个旋转弦的截面。我们发现,在高能区的截面是用第一类修正的贝塞尔函数表示的,其阶数由角动量给出。我们还从四点振幅的分波展开得到了类似的公式。截面的渐近行为与弦的一个众所周知的形状因子是一致的。

英文摘要:

We calculate production cross sections of a single rotating string from a collision of two light states in bosonic string theory. We find that the cross sections are written in terms of the modified Bessel function of the first kind with the degree given by the angular momentum in the high energy regime. We also obtain a similar formula from the partial wave expansion of four point amplitudes. Asymptotic behavior of the cross sections is consistent with a well known form factor of a string.
