非有理共形理论的圆盘单点函数

Disk one-point function for non-rational conformal theories

Juan Pablo Babaro, Gaston Giribet

摘要:

本文研究了一类非有理共形场论在共形边界存在下的无限族。最近在arXiv:0803.2099中提出的这些理论由两个实数(b,m)参数化,使得相应的中心荷c_{b,m}由c_{b,m} =3+6(b+b^{-1}(1-m))^{2}给出。对于磁盘的几何形状,我们明确地计算的期望值的情况下,m \in Z的批量顶点操作,使结果减少到刘维一点函数时,m=0。我们用两种不同的方法计算了圆盘单点函数,得到了完全一致的结果,并给出了路径积分和自由场导数的详细计算结果。

英文摘要:

We consider an infinite family of non-rational conformal field theories in the presence of a conformal boundary. These theories, which have been recently proposed in arXiv:0803.2099, are parameterized by two real numbers (b,m) in such a way that the corresponding central charges c_{b,m} are given by c_{b,m}=3+6(b+b^{-1}(1-m))^{2}. For the disk geometry, we explicitly compute the expectation value of a bulk vertex operator in the case m \in Z, such that the result reduces to the Liouville one-point function when m=0. We perform the calculation of the disk one-point function in two different ways, obtaining results in perfect agreement, and giving the details of both the path integral and the free field derivations.
