Scenario for Seeding a Singularity in $d = 2$ String Black Hole with Tachyon
Abstract
The string admits a black hole solution and also a singular solution when tachyon back reaction is included. It is of importance to know if the former solution can evolve into a later one. An explicit solution describing this process is difficult to obtain. We present here a scenario in which such an evolution is very likely to occur. In essence, it takes place when a derivative discontinuity is seeded in the dilaton field by an incident tachyon pulse. An application of this scenario to dimensional toy models suggests that a black hole can evolve into a massive remnant, strengthening its candidacy for the end state of a black hole.
