Tachyon Field Quantization and Hawking Radiation

TL;DR

This paper quantizes the tachyon field in a 2D black hole background, calculates the resulting Hawking radiation, and finds that tachyons produce a larger thermal flux than conformal matter, with massive scalars uncoupled to the dilaton contributing negligibly.

Contribution

It introduces a method for quantizing tachyon fields in black hole backgrounds and compares their Hawking radiation to that of conformal matter.

Findings

Tachyon fields produce a larger Hawking radiation flux than conformal matter.

Massive scalar fields not coupled to the dilaton do not significantly contribute to thermal radiation.

Quantization of tachyon fields in this context is feasible and yields measurable effects.

Abstract

We quantize the tachyon field in a static two dimensional dilaton gravity black hole background,and we calculate the Hawking radiation rate. We find that the thermal radiation flux, due to the tachyon field, is larger than the conformal matter one. We also find that massive scalar fields which do not couple to the dilaton, do not give any contribution to the thermal radiation, up to terms quadratic in the scalar curvature.
