High-energy asymptotics of D-brane decay amplitudes from Coulomb gas electrostatics
arXiv:1008.4743 · doi:10.1103/PhysRevD.82.126009
Abstract
We study the high-energy limit of tree-level string production amplitudes from decaying D-branes in bosonic string theory, interpreting the vertex operators as external charges interacting with a Coulomb gas corresponding to the rolling tachyon background, and performing an electrostatic analysis. In particular, we consider two open string - one closed string amplitudes and four open string amplitudes, and calculate explicit formulas for the leading exponential behavior.
