Curvaton reheating in tachyonic braneworld inflation

Abstract

The curvaton reheating in a tachyonic braneworld inflationary universe model with an exponential potential is studied. We have found that the energy density in the kinetic epoch, has a complicated dependencies of the scale factor. For different scenarios the temperature of reheating is computed, finding an upper limit that lies in the range ${10}^{14}$--${10}^{16}$ GeV.
