One-Loop String Diagram. Shown is the diagram for an open string, whose end points are fixed on two different -branes, propagating in a loop, being the time variable on the world sheet. Alternatively, interchanging with , the same diagram can be interpreted as a closed string being exchanged between the two -branes.
