One-loop Kähler Metric of Calabi-Yau Orientifolds

Marcus Berg (Karlstad University)


I will give some introduction to the general topic of string effective actions in orientifolds with D-branes, and discuss the evaluation of string one-loop contributions to the Kähler metric of closed string moduli in toroidal minimally supersymmetric (Calabi-Yau) orientifolds with D-branes. The focus is on poorly understood N = 1 contributions that a priori receive contributions from all massive string states.
