本文用围道积分方法导出了平面波光锥弦场论中立方顶点的精确玻色Neumann矩阵。这简化了顶点的原始推导。特别是,诺依曼矩阵是用\mu变形的Gamma函数来表示的,从而将它们转换成一种形式,优雅地推广了众所周知的平坦空间解。\mu-变形的Gamma函数的渐近性允许人们确定包括指数校正的Neumann矩阵的大\mu行为。我们提供了一个显式表达式的第一个指数校正,并提出了一个猜想,为后续的指数校正项。
The exact bosonic Neumann matrices of the cubic vertex in plane-wave light-cone string field theory are derived using the contour integration techniques developed in our earlier paper. This simplifies the original derivation of the vertex. In particular, the Neumann matrices are written in terms of \mu-deformed Gamma-functions, thus casting them into a form that elegantly generalizes the well-known flat-space solution. The asymptotics of the \mu-deformed Gamma-functions allow one to determine the large-\mu behaviour of the Neumann matrices including exponential corrections. We provide an explicit expression for the first exponential correction and make a conjecture for the subsequent exponential correction terms.
