Gauge Fields on Tachyon Matter
Akira Ishida, Shozo Uehara
TL;DR
This paper investigates gauge fields on tachyon matter within boundary string field theory, finding no plane wave solutions at large times, which supports the idea that tachyon matter does not support gauge field excitations.
Contribution
It demonstrates the absence of gauge field excitations on tachyon matter at late times, aligning with Sen's conjecture.
Findings
No plane wave solutions for gauge fields at large times
Gauge fields do not excite on tachyon matter
Supports the idea that tachyon matter is non-dynamical for gauge fields
Abstract
We study the rolling tachyon including the gauge fields in boundary string field theory. We show that there are no plane wave solutions for the gauge fields for large time. The disappearance of the plane wave solutions indicates that there are no excitations of the gauge fields on the tachyon matter, which is consistent with the Sen's conjecture.
