摘要：

We find the exact spectrum of a class of quarter BPS dyons in a generic N = 4 supersymmetric Z(N) orbifold of type IIA string theory on K3 x T-2 or T-6. We also find the asymptotic expansion of the statistical entropy to first non-leading order in inverse power of charges and show that it agrees with the entropy of a black hole carrying same set of charges after taking into account the effect of the four derivative Gauss-Bonnet term in the effective action of the theory.
