Thermal hybrid inflation in brane world

In conventional scenario of thermal inflation, the requirement from the reheating temperature puts a lower bound on the mass of the inflaton field. At the same time, the mass of the inflaton field and the height of the potential during thermal inflation is intimately related. With these conditions, the conventional models for thermal inflation are quite restricted. Naively, one may expect that the above constraints may be removed if thermal inflation is realized within the setups for hybrid inflation. In this respect, constructing a realistic model for thermal hybrid inflation seems interesting. We consider this problem in the brane world and show that thermal inflation can become free of the above restrictions.
