Tachyons in the Galilean limit

Abstract

The Souriau massless Galilean particle of "colour" kk and spin ss is shown to be the Galilean limit of the Souriau tachyon of mass m=ikm = ik and spin ss. We compare and contrast this result with the recent Galilean limit of the Nambu-Goto string and the Green-Schwarz superstring.
