AI中文摘要:
D1D5 CFT在BPS态上存在电荷集中谜题,其形式与$\boldsymbol{\textit{N}}=4$ SYM的类似但更简单。我们研究D1D5 CFT中来自超荷上同调的1/4-BPS算子的手征代数,以及由此产生的有理关联函数。利用交叉对称性和该手征代数,我们为一般耦合与有限中心电荷下、远离电荷集中轨迹的1/4-BPS态族的存在性提供了非微扰证明。我们进一步探讨其对D1D5 CFT中BPS混沌的可能影响,并计算了orbifold点处的后期BPS平台。
英文摘要:
The D1D5 CFT exhibits a charge concentration puzzle for BPS states, similar to, but simpler than, that of $\mathcal{N}=4$ SYM. We consider the chiral algebra of 1/4-BPS operators in the D1D5 CFT arising from a supercharge cohomology, and the resulting rational correlators. Using crossing symmetry and this chiral algebra, we establish a non-perturbative proof of the existence of a family of 1/4-BPS states away from the charge concentration locus for general coupling and finite central charge. We further discuss possible implications for BPS chaos in the D1D5 CFT and compute a late-time BPS plateau at the orbifold point.
