A 1/4-BPS chiral algebra in D1D5: from charge concentration to BPS chaos

Alexandre Belin, Suzanne Bintanja, Alessandra Gnecchi +2

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 i…
