Lienard-Wiechert potentials for charged tachyons and several remarks on the tachyon Cherenkov radiation

TL;DR

This paper derives the Lienard-Wiechert potentials for charged tachyons, finds they are twice as large as for normal particles, and discusses implications for tachyon Cherenkov radiation, including its angle and intensity.

Contribution

It provides the first derivation of Lienard-Wiechert potentials for charged tachyons and compares their magnitude to those of ordinary particles.

Findings

Tachyon Lienard-Wiechert potentials are twice as large as for normal particles.

Tachyon Cherenkov radiation angle follows the same formula as for ordinary particles.

Remarks on the intensity of tachyon Cherenkov radiation are included.

Abstract

The Lienard-Wiechert potentials for charged tachyons are deduced in this note. They turn out to be twice as large as compared to the corresponding potentials for ordinary particles. Several remarks are made on tachyon Cherenkov radiation and its intensity. In particular, it follows in a straightforward way from the derivation of the Lienard-Wiechert potentials that the tachyon Cherenkov radiation angle obeys the same formula as that for ordinary particles.
