This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). The Standard Model of elementary particles and cosmology describes remarkably well the evolution of the Universe starting from one-trillionth of a second after the Big Bang up to the present day. Despite this huge success, several fundamental questions remain unanswered: What is dark matter? Why is there more matter than antimatter in the Universe? Why are neutrinos massive? Solving these mysteries requires an understanding of what happened before one-trillionth of a second after the Big Bang. The tool enabling us to dive this far back into the Universe's history has only recently been provided by the first successful detection of gravitational waves. A primordial stochastic gravitational wave background, although not yet discovered, is expected to carry information precisely about the very early period of the Universe and is the subject of this proposal. This award supports Dr. Fornal at Barry University to construct and investigate well-motivated extensions of the Standard Model which solve the outstanding problems in particle physics (Dark matter, Matter-antimatter asymmetry, and Neutrino masses) which can be tested in present and future gravitational wave experiments. The project will provide substantial contributions to advancing knowledge, training future generations of scientists and highly specialized professionals acquainted with sophisticated mathematical methods and conveying physics ideas to nonscientists through the planned outreach activities. Given the gender and demographic diversity of Barry University, the project will significantly affect women and other groups underrepresented in the scientific community, who will receive training and acquire skills preparing them for advanced-degree programs in science, increasing their competitiveness on the academic and industrial job market, and improving their admission rate into doctoral programs.The goal of the project is to produce a mapping between the parameter space of the most attractive models of elementary particles accessible in gravitational wave detectors, and the parameter space which can be probed in other experiments. The new particle physics models considered are hypothetical, but their predictions will be verifiable in current and upcoming gravitational wave experiments. Combined with a positive signal from gravitational wave detectors, the results of this project would provide a breakthrough in understanding the structure of the Universe. The educational goal is to establish an energetic and creative group of young physics researchers among Barry University undergraduates. In addition, through presenting the results at international conferences and meetings of the American Physical Society, those students will be exposed to world-class scientists working in STEM fields, which will offer them various career networking opportunities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项是根据2021年《美国救援计划法》（公法117-2）全部或部分资助的。 基本颗粒和宇宙学的标准模型非常好的描述了宇宙的演变，从大爆炸之后的一千万千万千万到现在。尽管取得了巨大的成功，但几个基本问​​题仍未得到解决：什么是暗物质？为什么在宇宙中比反物质还要多？为什么中微子大规模？解决这些谜团需要了解大爆炸之后的一千万千万千万亿千万。该工具使我们能够在宇宙的历史上深入研究，直到最近才通过首次成功检测引力波才提供。原始的随机引力背景虽然尚未发现，但仍被期望准确地携带有关宇宙早期时期的信息，并且是该提案的主题。 该奖项支持Barry University的Fornal博士构建和研究标准模型的良好动机扩展，该模型解决了粒子物理学（暗物质，物质 - 抗逆点不对称和中微子肿块）的杰出问题，这些问题可以在当前和未来的重力波实验中进行测试。 该项目将为促进知识，培训子孙后代的科学家和高度专业的专业人员提供实质性贡献，并通过计划的外展活动将物理思想传达给非敏感主义者。考虑到巴里大学的性别和人口多样性，该项目将显着影响妇女和其他群体在科学界的人数不足，他们将获得培训和获取技能，为他们为科学的高级学位计划做好准备，将其在学术和工业工作市场上提高竞争力，并在学术和工业工作市场上竞争，并将其录取率在该项目中的元素范围内的元素范围内的元素范围内置于元素上。检测器和可以在其他实验中探测的参数空间。考虑的新粒子物理模型是假设的，但是它们的预测将在当前和即将进行的引力波实验中进行验证。结合引力波检测器的正信号，该项目的结果将为理解宇宙的结构提供突破。教育目标是在巴里大学的大学生中建立一个充满活力的年轻物理研究人员。此外，通过在美国物理社会的国际会议和会议上介绍结果，这些学生将接触到在STEM领域工作的世界一流的科学家，这将为他们提供各种职业网络机会。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估来进行评估来通过评估来支持的。
