来自f（R）引力理论的大质量残余引力波：产生和潜在探测
Massive relic gravitational waves from f(R) theories of gravity: production and potential detection
摘要：
遗留引力波的随机背景的产生在文献中的各种著作中是众所周知的，在这些著作中，通过使用所谓的绝热放大零点涨落过程，已经表明早期宇宙的标准暴胀方案如何在原则上提供遗留引力波的独特谱。本文指出，一般情况下，f（R）引力理论产生第三大质量的引力波极化，并采用绝热放大的零点涨落过程分析了这种极化的原始产生。这样，以前的结果，其中只有特殊情况下的f（R）理论进行了分析，将被推广。质量的存在也可能在宇宙学中有重要的应用，因为引力波可以有质量的事实可能对宇宙的暗物质有贡献。这些遗迹引力波，这是由WMAP约束的上限，也被释放。在论文的最后，讨论了使用Virgo和LIGO等干涉仪探测如此大质量的引力波的可能性。
英文摘要：
The production of a stochastic background of relic gravitational waves is well known in various works in the literature, where, by using the so called adiabatically-amplified zero-point fluctuations process, it has been shown how the standard inflationary scenario for the early universe can in principle provide a distinctive spectrum of relic gravitational waves. In this paper, it is shown that, in general, f(R) theories of gravity produce a third massive polarization of gravitational waves and the primordial production of this polarization is analysed adapting the adiabatically-amplified zero-point fluctuations process at this case. In this way, previous results, where only particular cases of f(R) theories have been analysed, will be generalized. The presence of the mass could also have important applications in cosmology, because the fact that gravitational waves can have mass could give a contribution to the dark matter of the Universe. An upper bound for these relic gravitational waves, which arises from the WMAP constrains, is also released. At the end of the paper, the potential detection of such massive gravitational waves using interferometers like Virgo and LIGO is discussed.
