We study the inflation dynamics of generalized dilaton–axion models with a new Fayet–Iliopoulos (FI) term, where both real and imaginary parts of the ‘dilaton–axion’ super-field evolve. We find that the turn rate per Hubble parameter is about ##IMG## [http://ej.iop.org/images/0264-9381/37/20/205016/cqgab9bbcieqn6.gif] {$O\left({10}^{-2}\right)$} to ##IMG## [http://ej.iop.org/images/0264-9381/37/20/205016/cqgab9bbcieqn7.gif] {$O\left({10}^{-1}\right)$} while the square of effective mass of entropic perturbation is about ##IMG## [http://ej.iop.org/images/0264-9381/37/20/205016/cqgab9bbcieqn8.gif] {$O\left({10}^{-1}\right)$} . These results can be used for identifying the specific inflation pattern in the future observation.

带有新的Fayet-Iliopoulos（FI）项的广义Dilaton-Axion模型的双场充气

我们用新的Fayet-Iliopoulos（FI）术语研究广义的Dilaton-Axion模型的膨胀动力学，其中“ Dilaton-Axion”超场的实部和虚部都在演化。我们发现每个哈勃参数的转弯速率约为## IMG ## [http://ej.iop.org/images/0264-9381/37/20/205016/cqgab9bbcieqn6.gif] {$ O \ left（{ 10} ^ {-2} \ right）$}到## IMG ## [http://ej.iop.org/images/0264-9381/37/20/205016/cqgab9bbcieqn7.gif] {$ O \ left （{10} ^ {-1} \ right）$}，而熵扰动的有效质量的平方约为## IMG ## [http://ej.iop.org/images/0264-9381/37/20 /205016/cqgab9bbcieqn8.gif] {$ O \ left（{10} ^ {-1} \ right）$}。这些结果可用于识别未来观察中的特定通胀模式。
