单值缺陷的块展开

On the bulk block expansion for a monodromy defect

J. S. Dowker

摘要:

对于自由场平坦单值缺陷,得到了相关器有限部分的公式,它是$(1-x)$和$(1-\ol x)$的双幂级数,其中$x$和$\ol x$是光锥坐标。它采取一系列的特殊形式在$(1-x)$系数有限和超几何函数的$1-\ol x$,并确定与块扩展。一个简单的表达式的系数的$(1-x)^n(1-\ol x)^m$长期,从而发现作为一个明确的功能的通量和尺寸。给出了几个典型的例子,通过一个变换,可以将块扩展写成Appell $F_3$函数,从而简化了块扩展。

英文摘要:

For a free--field flat monodromy defect, a formula for the finite part of the correlator is obtained as a double power series in $(1-x)$ and $(1-\ol x)$ where $x$ and $\ol x$ are lightcone coordinates. It takes the particular form of a series in $(1-x)$ with coefficients finite sums of hypergeometric functions of $1-\ol x$ and is identified with a bulk block expansion. A simple expression for the coefficient of the $(1-x)^n(1-\ol x)^m$ term is thereby found as an explicit function of the flux and dimension. Some typical examples are presented.A transformation allows the bulk block expansion to be written as an Appell $F_3$ function which has simplifying consequences.
