Fernando A. Flor is awarded an NSF Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship to conduct a program of research and education at Yale University. Flor will develop models of the formation of composite particles in the early universe using data from the ALICE experiment at CERN in Geneva, Switzerland and from the STAR experiment at Brookhaven National Laboratory on Long Island, New York. Both experiments use collisions of heavy ions to produce small droplets of Quark Gluon Plasma (QGP) at extremely high temperatures that mimic the conditions of the early universe, about one second after the Big Bang. The goal of the research is to understand the mechanism by which the QGP loses energy and forms the neutrons and protons that become normal matter, and how that mechanism is affected by different quarks. In addition, Flor will expand the University of Houston NuSTEAM effort, which connects University of Houston undergraduates with Brookhaven National Laboratory, to Yale University.Relativistic heavy ion collisions serve as a looking glass for probing and understanding the mechanisms governing the strong interaction between quarks and gluons emerging at the early stages of the Universe.The purpose of this project is threefold:1.) To elucidate the reigning mechanisms generating the strong interaction of matter present one second after the Big Bang.2.) To produce a sustainable and inclusive pedagogical outreach platform within the Experimental Heavy ion Physics community through which underrepresented minorities gain access to the field early in their academic careers.3.) To generate a paradigm focused on the overall ascent of underrepresented minority groups into the scientific community.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.

费尔南多弗洛尔被授予NSF数学和物理科学上升博士后研究奖学金，在耶鲁大学进行研究和教育计划。 弗洛尔将利用瑞士日内瓦欧洲核子研究中心的ALICE实验和纽约长岛布鲁克海文国家实验室的星星实验的数据，开发早期宇宙中复合粒子形成的模型。 这两个实验都使用重离子的碰撞在极高的温度下产生夸克胶子等离子体（QGP）的小液滴，模拟早期宇宙的条件，大约在大爆炸后一秒。 这项研究的目的是了解QGP失去能量并形成中子和质子成为正常物质的机制，以及该机制如何受到不同夸克的影响。 此外，Flor将把休斯顿大学NuSTEAM项目扩展到耶鲁大学，该项目将休斯顿大学本科生与布鲁克海文国家实验室联系起来。相对论重离子碰撞是探索和理解宇宙早期出现的夸克和胶子之间强相互作用机制的镜子。该项目的目的有三个：1）阐明大爆炸后一秒物质强相互作用的主导机制。在实验重离子物理社区内建立一个可持续和包容性的教学推广平台，通过该平台，代表性不足的少数民族在学术生涯的早期就可以进入该领域。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
