利用递推关系求解劳里切拉弦散射振幅

Solving Lauricella String Scattering Amplitudes through Recurrence Relations

Sheng-Hong Lai, Jen-Chi Lee, Taejin Lee, Yi Yang

摘要:

我们证明了在三个快子和一个任意弦态的开玻色弦散射振幅(SSA)或Lauricella SSA之间存在着无穷多个对所有能量都有效的递推关系。此外,这些无穷多个递推关系可以用来解决所有的Lauricella SSA,并表示为一个单一的四个快子振幅。这些结果扩展了SSA在高能、固定角散射极限和Regge散射极限的可解性。

英文摘要:

We show that there exist infinite number of recurrence relations valid for all energies among the open bosonic string scattering amplitudes (SSA) of three tachyons and one arbitrary string state, or the Lauricella SSA. Moreover, these infinite number of recurrence relations can be used to solve all the Lauricella SSA and express them in terms of one single four tachyon amplitude. These results extend the solvability of SSA at the high energy, fixed angle scattering limit and those at the Regge scattering limit discovered previously.
