论文摘要
由于广告$ _3 \ times $ s $^3 \ times $ m $ _ {4} $，最近对II型字符串压实的最近感兴趣，这是由于ADS $ _3 $/cft $ _2 $对应关系的新进展，并且对新$ {\ cal n} =（4,0）$ supergravity $ supergravity $ supergravity selutions又有独立的搜索。在这项工作中，我们报告了一个新的小型$ {\ cal n} =（4,0）$保存扭曲广告$ _3 \ times $ s $^3 \ times $ cy $ cy $ _2 $压实IIB超级GRAVETION。该家族中的S $^3 $在CY $ _2 $上没有微不足道的纤维。我们展示了这些新解决方案如何提供最小的ungaig $ d = 5 $超级耦合到Abelian矢量多重组的IIB嵌入。我们还迈出了一些初步步骤，以识别双CFT $ _2 $候选人。具体而言，我们研究了自旋两和某些向量波动的kaluza-klein光谱，这些波动预计将对应力 - 能量张量，su（2）r电流（2）r电流和其他几个BPS操作员家族在双CFT $ _2 $中。
There has been considerable recent interest in type II string compactifications on AdS$_3\times$S$^3\times$M$_{4}$ due to both new progress in the AdS$_3$/CFT$_2$ correspondence and an independent search for new ${\cal N}=(4,0)$ supergravity solutions. In this work we report a new family of small ${\cal N}=(4,0)$ preserving warped AdS$_3\times$S$^3\times $CY$_2$ compactifications of type IIB supergravity. The S$^3$ in this family is non trivially fibered over the CY$_2$. We show how these new solutions provide a IIB embedding of minimal ungauged $d=5$ supergravity coupled to an Abelian vector multiplet. We also make a few initial steps towards the identification of dual CFT$_2$ candidates. Specifically, we study the Kaluza-Klein spectrum of the spin two and certain vector fluctuations that are expected to be dual to the stress-energy tensor, SU(2) R current and several other BPS operator families in the dual CFT$_2$.
