Bethe Salpeter方法中BFKL特征值的Hermite可分性
Hermitian Separability of BFKL eigenvalue in Bethe Salpeter approach
摘要:
我们认为Bethe Salpeter方法的BFKL进化,以自然地将在BFKL方法的埃尔米特分离性的属性。我们将所得的所有阶的BFKL本征值与谐波和的反射恒等式相结合,并推导出超对称N=4中最复杂的次-次-首阶BFKL本征值项。我们还提出了一种数值方法,用于从已知的共形自旋的特定值的结果中重建我们的计算中的未知函数。
英文摘要:
We consider the Bethe Salpeter approach to the BFKL evolution in order to naturally incorporate the property of the Hermitian Separability in the BFKL approach. We combine the resulting all order ansatz for the BFKL eigenvalue together with reflection identities for harmonic sums and derive the most complicated term of the next-to-next-to-leading order BFKL eigenvalue in SUSY N=4. We also suggest a numerical technique for reconstructing the unknown functions in our ansatz from the known results for specific values of confomal spin.
