标题： Dilaton-axion modular inflation in supergravity

摘要： 标量场和轴子在扩展的超引力和闭合的超弦理论中无处不在。我们提出了四维$N=1$超引力与手征标量场-轴子-goldstino超多重态耦合的新的模化膨胀模型，这些模型符合一些超弦宇宙学的必要条件。我们将模型参数调整以满足宇宙微波背景辐射的精确测量要求。我们使用模化不变的超势和渐近模化不变的Kähler势，并实现了高能标超对称破缺下的轴子稳定。 显示英文摘要

摘要： Dilaton and axion are ubiquitous in extended supergravities and closed superstrings. We propose new models of modular inflation in four-dimensional $N=1$ supergravity coupled to the chiral dilaton-axion-goldstino supermultiplet, which fit some necessary conditions of superstring cosmology. The model parameters are tuned to obey precision measurements of the cosmic microwave background radiation. We employ the modular-invariant superpotentials and asymptotically modular-invariant K\"ahler potentials, and achieve axion stabilization with high-scale supersymmetry breaking.
