Lauricella函数与精确弦散射振幅

The Lauricella Functions and Exact String Scattering Amplitudes

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

摘要:

我们发现三个快子和一个任意弦态的26维开玻色弦散射振幅(SSA)可以用SL(K+3,C)对称的D型Lauricella函数表示.结果,SSA和对称性或SSA之间的关系,不同的弦状态在各种限制以前计算可以重新导出。其中包括Gross在[1-3]中首先提出并在[4-9]中修正和证明的硬散射极限中的线性关系,与SL(5,C)对称性相关的Regge散射极限中的递推关系[19-21],以及最近发现的与SL(4,C)对称性相关的非相对论散射极限中的推广递推关系[24]。最后,作为应用,我们计算了SSA的一个新的递推关系,它对所有能量都是有效的。

英文摘要:

We discover that the 26D open bosonic string scattering amplitudes (SSA) of three tachyons and one arbitrary string state can be expressed in terms of the D-type Lauricella functions with associated SL(K+3,C) symmetry. As a result, SSA and symmetries or relations among SSA of different string states at various limits calculated previously can be rederived. These include the linear relations first conjectured by Gross [1-3] and later corrected and proved in [4-9] in the hard scattering limit, the recurrence relations in the Regge scattering limit with associated SL(5,C) symmetry [19-21] and the extended recurrence relations in the nonrelativistic scattering limit with associated SL(4,C) symmetry [24] discovered recently. Finally, as an application, we calculate a new recurrence relation of SSA which is valid for all energies.
