String creation and heterotic-type I duality

Research output: Contribution to journalArticlepeer-review


The BPS spectrum of type I string theory in a generic background is derived using the duality with the nine-dimensional heterotic string theory with Wilson lines. It is shown that the corresponding mass formula has a natural interpretation in terms of type I, and it is demonstrated that the relevant states in type I preserve supersymmetry. By considering certain BPS states for different Wilson fines an independent confirmation of the string creation phenomenon in the D0-D8 system is found. We also comment on the non-perturbative realization of gauge enhancement in type I, and on the predictions for the quantum mechanics of type I D0-branes.
