Abstract
The generalized cosmic Chaplygin model in the context of brane-inflationary background is being considered by taking the standard scalar field as matter field. We develop the modified first Friedmann equation and conservation equation under slow-roll approximations. We also discuss the feature of the generalized cosmic Chaplygin gas model in the presence of chaotic potential in the high-energy limit. Various inflationary parameters, such as slow-roll parameters, scalar and tensor power spectra, scalar spectral index and tensor-to-scalar ratio are evaluated. To this end, Planck results are used to constraint new parameters.
