Electrostatics approach to closed string pair production from a decaying D-brane
We consider the emission of two closed string tachyons from a decaying Dp-brane in bosonic string theory. We study the high-energy limit of the emission amplitude by using an analogue to electrostatics. The case where the emitted strings have equal energies is analyzed in detail, and we obtain a rel...

| description | We consider the emission of two closed string tachyons from a decaying Dp-brane in bosonic string theory. We study the high-energy limit of the emission amplitude by using an analogue to electrostatics. The case where the emitted strings have equal energies is analyzed in detail, and we obtain a relatively simple result for the emission amplitude. We identify expected poles for s- and t-channel emission. In the high-energy limit, the amplitude decays exponentially ({approx}e{sup -2{pi}}{sup {omega}}) or faster in the energies {omega} of the closed strings. |
