论文摘要
没有奇异尺度极限的手性弦具有与相应的常规封闭串相同的临界维度。因此，其中央电荷将与共形规格中的常规对应物相同。在这里，我们将重新检查奇异的Hohm-Siegel-Zwiebach限制中手性弦的临界维度。对相应可能的应力张量的操作乘积扩展（OPE）的直接计算表明，在采用单数极限时，中心电荷项与其常规对应物不同。坐标重新构造没有在世界表上进行保形转换，而是提供了一组准文字映射。
The chiral string without a singular gauge limit is argued to have the same critical dimension as its corresponding conventional closed string. Thus, its central charge would be the same as its conventional counterpart in the conformal gauge. Here, we would re-examine the critical dimension of the chiral string in the singular Hohm-Siegel-Zwiebach limit. A straight forward calculation of the operator product expansion (OPE) of the corresponding would-be stress tensor shows that the central charge term is not the same as its conventional counterpart when taking the singular limit. Instead of having a conformal transformation on the worldsheet, the coordinate reparametrization provides a set of quasiconformal mappings.
