Abstract
We study the dynamics of parallel branebrane and braneantibrane scattering in string theory in flat spacetime focusing on the pair production of open strings that stretch between the branes We are particularly interested in the case of scattering at small impact parameter b l s where there is a tachyon in the spectrum when a brane and an antibrane approach within a string length Our conclusion is that despite the tachyon branes and antibranes can pass through each other with only a very small probability of annihilating so long as g s is small and the relative velocity v is neither too small nor too close to 1 Our analysis is relevant also to the case of charged open string production in worldvolume electric fields and we make use of this Tdual scenario in our analysis We briefly discuss the application of our results to a stringy model of inflation involving moving branesThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
