Investigating Cosmic Inflation and Dark Energy in blended models of Particle Theory and Modified Gravity

我们的目标是研究模型建立宇宙膨胀和暗能量，可能在一个单一的理论框架，采用现实的粒子理论超越标准模型和修改的引力理论，如F（R）引力。我们打算对暴胀观测量（标量谱指数，张量与标量比）以及CDM之外的暗能量特征进行具体的预测，例如状态参数方程及其运行，在不久的将来进行探测，例如欧几里得和Nancy Grace Roman卫星。与观察结果的对比将提供对理论背景的深入了解。重点将放在解决宇宙学的开放问题，如哈勃和增长的紧张局势，并对引力波的观测签名，如放大的原始引力波从通货膨胀（或kination）或来自原始黑洞（可能是暗物质），在不久的将来由丽莎的LIGO/Virgo直接探测，或由即将到来的CMB观测间接探测，例如BICEP，蜘蛛西蒙斯

We aim to study model-building cosmic inflation and dark energy, possibly in a single theoretical framework, employing realistic particle theories beyond the standard model and also modified gravity theories, such as F(R) gravity. We intend to produce concrete predictions regarding the inflationary observables (scalar spectral index, tensor to scalar ratio) as well as characteristics of dark energy beyond CDM, such as the equation of state parameter and its running, to be probed in the near future, e.g. by the EUCLID and Nancy Grace Roman satellites. Contrast with observations will provide insights on the theoretical background. Emphasis will be given on the resolutions of cosmological open questions, such as the Hubble and growth tensions, and on observational signatures of gravitational waves, such as amplified primordial gravitational waves from inflation (or kination) or from primordial black holes (which could be the dark matter), to be probed in the near future directly by LIGO/Virgo of LISA or indirectly by forthcoming CMB observations, e.g. BICEP, SPIDER, Simons.
