Abstract
The parameter space for A-term inflation is explored with W = λpp/pMPp−3. With p = 6 and λp~1, the observed spectrum and spectral tilt can be obtained with soft mass of order 102 GeV but not with a much higher mass. The case p = 3 requires λp~10−9 to 10−12. The ratio m/A requires fine-tuning, which may be justified on environmental grounds. An extension of the minimal supersymmetric standard model to include non-renormalizable terms and/or Dirac neutrino masses might support either A-term inflation or modular inflation.
