HETEROTIC MASSIVE EINSTEIN-YANG-MILLS-TYPE SYMMETRY AND WARD IDENTITY

Abstract

We show that there exist spontaneously broken symmetries for massive modes with transformation parameters theta((ab)) ([mu>upsilon]) theta((ab)) (mu) etc, containing both Einstein and E(8) circle times E(8) (or 50(32)) Yang-Mills indices in the 10D Heterotic string. The corresponding on-shell Ward identities are also constructed.
