Constraints on the generalized tachyon field models from latest observational data
Constraints on the generalized tachyon field models from latest observational data
We consider constraints on generalized tachyon field (GTF) models from latest observational data (including 182 gold SNIa data, the shift parameter, and the acoustic scale). We obtain at 68.3% confidence level Ωm = 0.37 ± 0.01, k0 = 0.09−0.03+0.04, α = 1.8−0.7+7.4 (the best fit values of the parameters) and …
