利用对数共形场理论研究了手性点（手性点）的拓扑质量引力。引入了两个新的张量场的ψ new和X，作为在手性点上传播的物理场的候选。然而，我们证明了（ψnew,ψL）形成了非物理场的偶极鬼偶对，并且X不是初级场。这意味着在手性点上没有物理上的传播自由度。
We study the topologically massive gravity at the chiral point (chiral gravity) by using the logarithmic conformal field theory. Two new tensor fields of ψnewand X are introduced for a candidate of propagating physical field at the chiral point. However, we show that (ψnew,ψL) form a dipole ghost pair of unphysical fields and X is not a primary. This implies that there is no physically propagating degrees of freedom at the chiral point.
