Noncommutative KKLMMT Model

Abstract

In the noncommutative space-time the fine tuning in KKLMMT model can be significantly released and a nice running of spectral index fitting the WMAP three year data can be achieved. The fitting results show that the noncommutative mass scale is roughly $5\times 10^{14}$ Gev. The string mass scale is higher than the noncommutative scale unless the string coupling is smaller than $10^{-10}$.
