- 論文の詳細を見る
Banks and Dine have recently shown that the M-theory naturally accommodates the Peccei-Quinn axion. since the decay constant F_a of the axion is as large as F_a ≃10^<15> -10^<16> GeV, the halo axion will be difficult to detect in future axion-search experiments. However, we show that isocurvature fluctuations of the M-theory axion produced at the inflationary epoch will most likely be detectable in future satellite experiments on anisotropies of the cosmic microwave background radiation.
