Large non-Gaussianity generated after D-term Inflation by Right-Handed
  Sneutrino Curvaton
  In this paper, we consider large non-Gaussianity generated after D-term
inflation in the case that the adiabatic curvature perturbation produced is
dominated by a right-handed (RH) sneutrino curvaton. The cosmic string problem
can also be evaded with around 10% contribution to the CMB power spectrum and
the spectral index $n_s \simeq 1$. The non-Gaussianity produced can be as large
as $10<f_{NL}<100$ for the right-handed sneutrino mass being around $m_\Phi=10
{GeV}$ with the Yukawa coupling $\lambda_\nu \sim 10^{-10}$. In this case, the
lightest neutrino mass is $10^{-10}{eV}$ which favors RH sneutrino
leptogenesis.
