Arithmetic of decay walls through continued fractions: a new exact dyon counting solution in N=4 CHL models

We use continued fractions to perform a systematic and explicit characterization of the decays of two-centred dyonic black holes in 4DN = 4 heterotic Z(N) CHL models. Thereby we give a new exact solution for the problem of counting decadent dyons in these models.
