Query: Towards the One-loop Kahler Metric of Calabi-Yau Orientifolds   We evaluate string one-loop contributions to the Kahler metric of closed
string moduli in toroidal minimally supersymmetric (Calabi-Yau) orientifolds
with D-branes. We focus on the poorly understood N=1 sectors that receive
contributions from all massive string states.
