Abstract:
We study the twisted partition function of quarter BPS states in CHL models and show that for a large class of single-centered black holes, the degeneracy of microstates is given by the Fourier coefficients of mock Jacobi forms. We identify a class of charges, for which the above identification does not hold. We also present the multiplicative lift construction of the partition function and comment on the additive lift of the same.
