Analyzed effects of Born-Infeld electromagnetic fields on tachyon decay.
Provided insights into D-brane decay dynamics.
Abstract
We study decay of a flat unstable D-brane in the context of boundary string field theory action. Three types of homogeneous rolling tachyons are obtained without and with Born-Infeld type electromagnetic field.
