Accelerating Cosmological Models for an Interacting Tachyon
U. Filobello, A. de la Macorra
We study the cosmological evolution of a tachyon scalar field T with a Dirac- Born- Infeld type lagrangian and potential V (T) coupled to a canonically normalized scalar field with…

Interacting Tachyon: generic cosmological evolution for a tachyon and a scalar field
A. de la Macorra, U. Filobello
We study the cosmological evolution of a tachyon scalar field T with a Dirac-Born-Infeld type lagrangian and potential V(T) coupled to a canonically normalized scalar field ϕwith a…

The Mass, Normalization and Late Time behavior of the Tachyon Field
A. de la Macorra, U. Filobello, G. German
We study the dynamics of the tachyon field . We derive the mass of the tachyon as the pole of the propagator which does not coincide with the standard mass given in the literatu…
