We focus on non-renormalizable couplings h between the moduli field and the field that becomes light at the ESP. Considering [ higher dimensional interaction, we find that particle production is significant in a 3 large area, which is even larger than the area that is expected from a renormalizable v 1 interaction. It is possible to find this possibility from a trivial adiabatic condition; 5 however the quantitative estimation of particle production and trapping of the field in 7 motion are far from trivial. In this paper we study particle production and trapping 4 . in detail, using both the analytical and numerical calculations, to find a clear and 0 intuitive result that supports trapping in a vast variety of theo
