Warm tachyonic inflation in strong dissipative regime: A study with exp[-T2] potential

Abstract

Warm inflation is an interesting possibility of describing the early universe. The basic idea of warm inflation is that a scalar field called inflaton is coupled to several other fields in the inflationary era. In this paper, we study the warm tachyonic inflation with exp[-T2] potential. In the present model the dissipation coefficient has been considered as constant. We find that the model can successfully predict the cosmological observables within the experimental bounds.
