Properties of extremal CFTs with small central charge
Francesca Ferrari, Sarah M. Harrison
We analyze aspects of extant examples of 2d extremal chiral (super)conformal field theories with . These are theories whose only operators with dimension smaller or equal…
K3 Elliptic Genus and an Umbral Moonshine Module
Vassilis Anagiannis, Miranda C. N. Cheng, Sarah M. Harrison
Umbral moonshine connects the symmetry groups of the 23 Niemeier lattices with 23 sets of distinguished mock modular forms. The 23 cases of umbral moonshine have a uniform relation…
Attractive Strings and Five-Branes, Skew-Holomorphic Jacobi Forms and Moonshine
Miranda C. N. Cheng, John F. R. Duncan, Sarah M. Harrison +3
We show that certain BPS counting functions for both fundamental strings and strings arising from fivebranes wrapping divisors in Calabi--Yau threefolds naturally give rise to skew…
Symmetries of the refined D1/D5 BPS spectrum
Nathan Benjamin, Sarah M. Harrison
We examine the large 1/4-BPS spectrum of the symmetric orbifold CFT Sym deformed to the supergravity point in moduli space for and . We consider refinement…
