In this paper we show that it is possible to achieve successful hilltop inflation in which the inflaton is identified as the modulus field in a modular invariant theory. The dilaton plays a crucial role in shaping the potential. Modular invariant gaugino condensation provides the mechanism for the modulus stabilisation after inflation. The inflationary trajectory lies on the lower boundary of the fundamental domain of the modulus field τ. Inflation starts near the fixed point τ = i, and ends at a point near τ = ω, which is the global de Sitter vacuum. We investigate the allowed parameter space for successful modular invariant hilltop inflation.

模块化不变山顶通货膨胀


在本文中，我们证明了成功实现山顶暴胀是可能的，其中暴胀子被识别为模不变理论中的模量场。膨胀子在塑造势能方面发挥着至关重要的作用。模不变高吉诺凝聚提供了膨胀后模量稳定的机制。暴胀轨迹位于模量场 τ 基本域的下边界。暴胀开始于固定点 τ = i 附近，结束于 τ = ω 附近的点，即全局德西特真空。我们研究了成功的模块化不变山顶膨胀所允许的参数空间。
