Scattering threshold for radial defocusing-focusing mass-energy double critical nonlinear Schrodinger equation in $dgeq 5$

We extend the scattering result for the radial defocusing-focusing mass-energy double critical nonlinear Schrodinger equation in $dleq 4$ given by Cheng et al. to the case $dgeq 5$. The main ingredient is a suitable long time perturbation theory which is applicable for $dgeq 5$. The paper will therefore give a full characterization on the scattering threshold for the radial defocusing-focusing mass-energy double critical nonlinear Schrodinger equation in all dimensions $dgeq 3$.
