Black Holes as a Window into our Universe: Theory and Phenomenology

该奖项资助纽约州立大学布法罗分校的Dejan Stojkovic教授的研究活动。Stojkovic教授的研究目标是解决粒子物理学、宇宙学和引力前沿的开放性问题。 特别是，这项研究将面向理解最近发现的希格斯粒子的性质和早期宇宙条件之间相互作用的重要方面。 Stojkovic教授还致力于研究早期宇宙中可能存在的某些旋转黑洞的性质，从而在我们对引力最基本的理解方面取得重要进展。 因此，该项目通过促进美国基础科学的发展来促进国家利益。 该项目还将为下一代科学家提供良好的培训，并将进一步发展创新的新思想，在许多科学学科中具有多种应用。 从技术上讲，这项研究将侧重于以下主题。 首先，Stojkovic教授将限制原始黑洞的丰度，包括旋转的影响，这涉及（i）计算各种质量和角动量的原始黑洞的发射光谱，包括夸克和胶子的强子化以及随后的强子衰变为光子，（ii）将结果与公认的天体物理观测进行对比，以及（iii）应用新建立的极限，以改进通过黑洞合并或直接霍金辐射产生引力波的预测。 Stojkovic教授还将通过以下方式将精确的希格斯物理学与引力和宇宙学联系起来：（i）在引力存在的情况下改进和扩展对虚假希格斯真空衰变的原始分析，（ii）将双环希格斯有效势和原始黑洞质量联系起来，以及（iii）限制标准模型之外的物理学。 还将开发进行这种分析所需的改进的理论计算和计算工具。 为了提取精确的信息，将进行天体物理观测和实验室实验的理论预测。 这项研究还将与教育和外联结合起来。 所开发的工具将向公众提供，以使广大研究界受益。 该项目还将为高中、本科和研究生阶段的学生提供一个良好的培训基地，为他们未来可能从事的科学事业做好准备。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award funds the research activities of Professor Dejan Stojkovic at SUNY at Buffalo.The goal of the research of Professor Stojkovic is to address open questions at the frontiers of particle physics, cosmology, and gravity. In particular, this research will be oriented toward understanding important aspects of the interplay between the properties of the recently-discovered Higgs particle and conditions in the early universe. Professor Stojkovic also aims to investigate the properties of certain rotating black holes which might have existed in the early universe, and thereby make important progress in our understanding of gravity at its most fundamental level. As such, this project advances the national interest by fostering the development of basic science within the United States. This project will also provide excellent training for the next generation of scientists and will further the development of innovative new ideas with manifold applications across many scientific disciplines. More technically, this research will focus on the following topics. First, Professor Stojkovic will constrain the abundance of primordial black holes including the effects of rotation, which involves (i) calculating the emission spectra for primordial black holes of various masses and angular momenta, including hadronization of quarks and gluons and subsequent hadron decay into photons, (ii) contrasting the results with well-established astrophysical observations, and (iii) applying the newly established limits in order to improve the predictions for the production of gravitational waves through black-hole mergers or by direct Hawking radiation. Professor Stojkovic will also connect precision Higgs physics with gravity and cosmology by (i) refining and extending the original analysis of the false Higgs vacuum decay in the presence of gravity, (ii) relating the two-loop Higgs effective potential and primordial black-hole masses, and (iii) constraining physics beyond the Standard Model. Improved theoretical calculations and computational tools which are needed to perform this analysis will also be developed. In order to extract precise information, theoretical predictions for astrophysical observations and lab experiments will be made. This research will also be integrated with education and outreach. The tools developed will be made publicly available for the benefit of the larger research community. This project will also provide an excellent training ground for students at the high-school, undergraduate, and graduate levels, preparing them for possible future career in science.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.
