- Abstract
We discuss the warm inflation in the presence of shaft potential , tachyon scalar field and the generalized form of dissipative coefficient . In this respect, we investigate the inflationary parameters (slow-roll parameters, number of e-folds, scalar-tensor power spectra, spectral indices, tensor-to-scalar ratio and running of scalar spectral index) in both strong and weak dissipative regimes. It is interesting to mention that our inflationary parametric results (tensor-scalar ratio, spectral index and running of spectral) are consistent with the recent observational data such as BICEP, WMAP and latest Planck data.
