标题： Solving the Cosmological Moduli Problem with Weak Scale Inflation

摘要： 许多超对称破缺模型涉及具有弱标度质量和 Planck 标度抑制耦合的粒子。这些粒子在早期宇宙中的相干产生会破坏核合成的成功预言。我们表明，这个问题可以通过一个短暂的弱标度暴胀来解决。此外，这种暴胀的膨胀子势能自然地源于导致宇宙学问题的相同假设。在这个场景中，成功的重子生成和大尺度结构形成的密度涨落的保存也是可能的。 显示英文摘要

摘要： Many models of supersymmetry breaking involve particles with weak scale mass and Planck mass suppressed couplings. Coherent production of such particles in the early universe destroys the successful predictions of nucleosynthesis. We show that this problem may be solved by a brief period of weak scale inflation. Furthermore the inflaton potential for such an inflation naturally arises from the same assumptions which lead to the cosmological problem. Successful baryogenesis and preservation of density fluctuations for large scale structure formation are also possible in this scenario.
