Abstract: In this paper, we show that if we extend D-term hybrid inflation by adding alight scalar field which couples to a waterfall field, large non-Gaussianitycan be generated at the end of inflation. Contribution of cosmic stringsgenerated after D-term inflation to the Cosmic Microwave Background CMBangular power spectrum can be as low as 10% and this also evade the spectralindex problem.
