Abstract
Recently, a class of large field inflaton potentials has been identified which begins with a power law potentials. In this model, initially relative fast roll lasting until a few e-folds in the horizon transits to the slow roll part potential with low power. Here, a question arises regarding the origin of the whipped inflation in 4D universe? We find the answer BIon system. Here a model is proposed that allows all parameters of this model to depend on the separation distance, tachyonic potential and wormholes between two branes in this system. These wormholes are formed due to collision between the spikes of brane and antibrane. We examine the whipped inflationary model against Planck and BICEP2 data and show that the model works.
