Structure In The Heterotic Matter Field Kahler Potential
James Gray
It has long been known that superpotential couplings in heterotic theories often vanish despite the absence of any known symmetry that would forbid them. We show that such structur…

Vanishing conditions for higher order couplings in heterotic theories
James Gray
For compactifications of heterotic string theory, we elucidate simple cohomological conditions that lead to the vanishing of superpotential n-point couplings for all n. These resul…
