标题： Inflation and Kahler Stabilization of the Dilaton

摘要： 在包含标量场的理论中尝试构建暴涨模型所面临的问题被阐明。 特别是，我基于一个弱耦合的异弦模型研究了标量场势的形状，今天以及在暴涨期间，假设修正的Kähler势负责标量场的稳定化。 虽然没有尝试具体的模型构建，但如果暴涨能量密度与规范玻色子凝聚尺度有关，那么标量场可能被稳定在接近今日值的位置，从而导致大统一理论（GUT）尺度耦合没有显著变化。 这种情况可以在非常广泛的模型中发生，并有助于为谱指数的标准预测提供一些合理性支持。 我解释了这一结果最终可以追溯到理论的超对称结构的原因。 显示英文摘要

摘要： The problems of attempting inflationary model-building in a theory containing a dilaton are explained. In particular, I study the shape of the dilaton potential today and during inflation, based on a weakly-coupled heterotic string model where corrections to the Kahler potential are assumed to be responsible for dilaton stabilization. Although no specific model-building is attempted, if the inflationary energy density is related to the scale of gaugino condensation, then the dilaton may be stabilized close enough to today's value that there is no significant change in the GUT scale coupling. This can occur in a very wide range of models, and helps to provide some justification for the standard predictions of the spectral index. I explain how this result can ultimately be traced to the supersymmetry structure of the theory.
