We argue that chaotic inflation with a running inflaton mass may give rise to the desired scenario where the process of fragmentation into inflatonic Q balls can actually take place even though there is total zero charge. We show that such inflatonic Q balls will reheat the Universe to a sufficiently low temperature via surface evaporation.4 pages, Talk given at SUSY-02, DESYHigh Energy Physics - Phenomenologytext
