This action funds Matthew Walters of Johns Hopkins University to conduct a research project in the Mathematical and Physical Sciences area during the summer of 2013 at the University of Tokyo's Kavli Institute for the Physics and Mathematics of the Universe in Kashiwa, Japan. The project title is "New Light Particles in the Early Universe." The host scientist is Hitoshi Murayama.This research project studies the effects of new light particle species on early universe phenomena, such as the synthesis of light elements and the production of residual background radiation. These effects are explored in an effective field theory approach, in order to provide constraints on theories in a model-independent fashion. In addition, this project develops calculational methods to determine the mass of new light particles which become nonrelativistic during the era of recombination, when electrons and protons began to form neutral atoms. These results have significant implications for theoretical models and future experimental research, both in cosmology and elementary particle physics, with the potential to discover new particles and physical phenomena.Broader impacts of an EAPSI fellowship include providing the Fellow a first-hand research experience outside the U.S.; an introduction to the science, science policy, and scientific infrastructure of the respective location; and an orientation to the society, culture and language. These activities meet the NSF goal to educate for international collaborations early in the career of its scientists, engineers, and educators, thus ensuring a globally aware U.S. scientific workforce. Furthermore, through this research project the Fellow is developing new analyses and applications for data from multiple observational experiments. The Fellow is both submitting these results for publication to aid experimental scientific collaborations in the use of current and future data and using them to educate the general population about current progress in physics and astronomy. In addition, the Fellow is sharing these methods of analysis with researchers in the host country and the U.S. to encourage further collaborations and extensions of this project.

这项行动为约翰·霍普金斯大学的马修·沃尔特斯（Matthew Walters）提供了资金，在2013年夏天在东京大学的卡夫利大学（Kavli）的卡夫利大学（Kavli）的宇宙王室Kashiwa的卡夫利大学（Kavli）大学的卡夫利大学（Kavli）大学，在日本喀西瓦（Kashiwa）进行了数学和物理科学领域的研究项目。 项目标题是“早期宇宙中的新光粒”。 宿主科学家是Hitoshi Murayama。该研究项目研究了新光颗粒物种对早期宇宙现象的影响，例如光元素的合成和残留背景辐射的产生。 这些效果是在有效的现场理论方法中探索的，以便以独立于模型的方式对理论构成约束。 此外，该项目还开发了计算方法来确定在重组时代，当电子和质子开始形成中性原子时，这些方法在重组时代变得非同性化。 这些结果对宇宙学和基本粒子物理学的理论模型和未来的实验研究具有重要意义，并有可能发现新的粒子和物理现象。各自位置的科学，科学政策和科学基础设施的简介；以及社会，文化和语言的方向。 这些活动符合NSF的目标，以在其科学家，工程师和教育工作者的职业生涯的早期对国际合作进行教育，从而确保全球意识的美国科学劳动力。 此外，通过该研究项目，研究员正在开发来自多个观察性实验的数据的新分析和应用。 该研究员都将这些结果提交出版，以帮助实验性科学合作，以使用当前和未来的数据，并使用它们来教育普通人群有关当前物理和天文学的进展。 此外，该研究员正在与东道国和美国的研究人员共享这些分析方法，以鼓励该项目的进一步合作和扩展。
