论文摘要
我们考虑D1-D5-P状态在D1-D5 Orbifold CFT的未介于的扇区中，其中一个种子CFT的副本对左移动的超符合原则感到兴奋。尽管在Orbifold点处是BPS，但由于该理论在模量空间中远离这一点时，此类状态仍可以“提升”。我们在此类状态的任意左移动维度$ h $的变形参数中以二阶的二阶计算此提升。该结果显示出有趣的普遍性，因为提升不取决于超符号主要的细节。它仅取决于维度。在大维限制中，提升尺度为$ \ sqrt {h} \，$;据观察，这种缩放似乎是D1-D5-P状态提升的通用特性。
We consider D1-D5-P states in the untwisted sector of the D1-D5 orbifold CFT where one copy of the seed CFT has been excited with a left-moving superconformal primary. Despite being BPS at the orbifold point, such states can `lift' as the theory is deformed away from this point in moduli space. We compute this lifting at second order in the deformation parameter for arbitrary left-moving dimension $h$ of this class of states. This result displays an interesting universality since the lifting does not depend on the details of the superconformal primary; it depends only on the dimension. In the large-dimension limit the lift scales as $\sqrt{h}\,$; it is observed that such scaling appears to be a universal property of the lift of D1-D5-P states.
