Chiral Multiplets in N=1 Dual String Pairs

Abstract

We compare the spectrum of chiral multiplets in the N=1 vacua of the heterotic string on a Calabi-Yau together with an $E_8\times E_8$ vector bundle and F-theory on a smooth Calabi-Yau fourfold. Under suitable restrictions we show agreement using an index-computation.
