  In this paper the existence of the thermal tachyons i.e. quanta of
temperature field, with is described in the theoretical frame of hyperbolic
thermal equation. The modified Lorentz transformation are developed. It is
argued that thermal tachyons can exist in accordance with modified Lorentz
transformation after change . The thermal tachyons fulfill the hyperbolic heat
transport equation and in principle can be created by attosecond laser pulses.
Key words: Tachyons; Thermal processes; Attosecond laser pulses.
