E + E $\rightarrow$ H
Abstract
Estrings arise from M2 branes suspended between an M5 brane and an M9 plane. In this paper we obtain explicit expressions for the elliptic genus of two Estrings using a series of string dualities. Moreover we show how this can be used to recover the elliptic genus of two $E_8\times E_8$ heterotic strings using the HoravaWitten realization of heterotic strings in Mtheory. This involves highly nontrivial identities among Jacobi forms, and is remarkable in light of the fact that Estrings are 'sticky' and form bound states whereas heterotic strings do not form bound states.
