Query: Spectrum of Dyons and Black Holes in CHL orbifolds using Borcherds Lift   The degeneracies of supersymmetric quarter BPS dyons in four dimensions and
of spinning black holes in five dimensions in a CHL compactification are
computed exactly using Borcherds lift. The Hodge anomaly in the construction
has a physical interpretation as the contribution of a single M-theory
Kaluza-Klein 6-brane in the 4d-5d lift. Using factorization, it is shown that
the resulting formula has a natural interpretation as a two-loop partition
function of left-moving heterotic string, consistent with the heuristic picture
of dyons in the M-theory lift of string webs.
