Collider tools and techniques applied to neutrino and early universe physics

粒子物理学正在进入一个激动人心的时代，中微子和引力波实验的新观测将为最小尺度下的粒子性质和最早时期的宇宙提供补充窗口。然而，在提高我们的计算精度和我们如何将物理模型与数据进行比较的严谨性方面，还有很多工作要做。大型强子对撞机项目已经运行了20多年，在理解、模拟和分析粒子相互作用方面，理论物理学取得了重大进展。许多这样的计算工具和软件可以有效地应用于中微子实验和早期宇宙物理。杰克·富兰克林将参与以下项目：利用ProtoDUNE数据实现了DUNE实验的快速探测器模拟。应用对撞机工具和技术（如喷流聚类算法）构建一个分析，以改进DUNE实验中的暗物质探测。应用射流聚类算法和射流拓扑来改进冰立方实验中的tau中微子探测。3. 构建一个代码来模拟中微子核子相互作用。此外，在他的博士学位中，他将对这些相互作用进行建模。了解这种相互作用并可靠地模拟它们对下一代中微子实验至关重要。这些项目的范围从现象学到理论。利用引力波和中微子数据之间的互补性作为评估大统一理论可行性的一种手段

Particle physics is entering an exciting era where new observations from neutrino and gravitational wave experiments will provide complementary windows into particles' nature at the smallest scales and the universe at the earliest times. However, there remains much to be done in improving the precision of our calculations and the rigour of how we compare our physics models to data. As the Large Hadron Collider programme has been running for more than 20 years, there have been momentous theoretical physics developments to understand, simulate and analyse particle interactions. Many such calculational tools and softwares can be effectively applied to neutrino experiments and early universe physics. Jack Franklin will engage in the following projects 1. Use ProtoDUNE data to implement a fast detector simulation of the DUNE experiment. Apply collider tools and techniques (such as jet clustering algorithms) to construct an analysis to improve dark matter detection at the DUNE experiment.2. Apply jet clustering algorithms and jet topologies to improve tau neutrino detection at the IceCube experiments. 3. Constructing a code to simulate neutrino nucleon interactions. Furthermore, in his PhD, he will model these interactions. Understanding such interactions and being to reliably simulate them is crucial for the next generation of neutrino experiments.These projects range from more phenomenological to theoretical.4. Exploit the complementarity between gravitational wave and neutrino data as a means of assessing the viability of Grand Unified Theories
