D-branes and production of strings

Research output: Contribution to journalArticlepeer-review


We review two types of D-branes processes where open strings are created. In the first type, a closed string incident on a collection of D-branes is converted into a number of open strings running along them. For the case of threebranes we compare the absorption rate with that in semiclassical gravity, and find exact agreement. The second type of process is creation of stretched open strings by crossing D-branes. We show that this is possible whenever a p-brane passes through an (8 - p)-brane positioned orthogonally to it. The extra attractive force exerted by the stretched open string is crucial for rinding that the net force cancels in this BPS system.
