| dc.description | A simple model of quintessential inflation with the modified exponential potential exp(-αϕ) [A + (ϕ-ϕ_0)^2] is analyzed in the braneworld context. Considering reheating via instant preheating, it is shown that the evolution of the scalar field ϕfrom inflation to the present epoch is consistent with the observational constraints in a wide region of the parameter space. The model exhibits transient acceleration at late times for 0.96 < A α^2 < 1.26 and 271 < ϕ_0 α< 273, while permanent acceleration is obtained for 2.3 10^{-8} < A α^2 < 0.98 and 255 < ϕ_0 α< 273. The steep parameter αis constrained to be in the range 5.3 < α< 10.8. | |
