通过曲率与物质的广义非最小耦合的再加热

Reheating via a generalized non-minimal coupling of curvature to matter

Orfeu Bertolami, Pedro Frazão, Jorge Páramos

摘要:

在这项工作中,人们表明,几何和物质之间的广义非最小耦合与Starobinsky暴胀兼容,并导致成功的预热过程,一个基于通过参数共振产生大质量粒子的再加热方案。该模型自然地扩展了通常的预热机制,它诉诸于{ \it ad-hoc}标量场$χ$的标量曲率相关的质量项,也包括以前研究的预热通道的基础上的非标准动力学项。

英文摘要:

In this work one shows that a generalized non-minimal coupling between geometry and matter is compatible with Starobinsky inflation and leads to a successful process of preheating, a reheating scenario based on the production of massive particles via parametric resonance. The model naturally extends the usual preheating mechanism, which resorts to an {\it ad-hoc} scalar curvature-dependent mass term for a scalar field $χ$, and also encompasses a previously studied preheating channel based upon a non-standard kinetic term.
