Abstract
We show that there exist two 27 and one \( \bold{\overline {27}} \) of E 6, net one D = 4, \( \mathcal{N} \) = 1 chiral matter supermultiplet as zero modes localized on the intersection of two 5-branes in the E 8 × E 8 heterotic string theory. The smeared intersecting 5-brane solution is used via the standard embedding to construct a heterotic background, which provides, after a compactification of some of the transverse dimensions, a five-dimensional Randall-Sundrum II like brane-world set-up in heterotic string theory. As a by-product, we present a new proof of anomaly cancellation between those from the chiral matter and the anomaly inflow onto the brane without small instanton.
