Asli Acar's PhD project is based on a Thomas Jefferson National laboratory "VeryStrange" proposal (UoY spokespersons Zachariou, Watts; ~150 scientists on the proposal) aimed to establish the spectrum of nucleon resonances containing two strange quarks (cascades) including their quantum numbers and decay branches. In a view of multiple recent exotic particles discoveries, exploration of cascade spectra become extremely important since it allows to link heavy quark systems with non-relativistic quarks to light quark systems with ultrarelativistic quarks, benchmarking the theory of strong interactions, Quantum ChromoDynamics (QCD), in the intermediate regime. A cascade baryons with two strange quark combined in a di-quark system are expected to behave very similar to a heavy-light mesons. Asli's analysis will verify the validity of this hypothesis. We expect her work to be realized as a very high impact paper. Asli will analyze CLAS-12 data collected in 2019-2022 which meanwhile got fully calibrated and cooked.Some part of her project will be concentrated on simulation of various reactions in CLAS-12 environment and theoretical data processing with the elements of AI.

Asli Acar 的博士项目基于托马斯·杰斐逊国家实验室的“VeryStrange”提案（UoY 发言人 Zachariou、Watts；该提案约有 150 名科学家），旨在建立包含两个奇怪夸克（级联）的核子共振谱，包括它们的量子数和腐烂的树枝。鉴于最近发现的多个奇异粒子，级联光谱的探索变得极其重要，因为它允许将具有非相对论夸克的重夸克系统与具有超相对论夸克的轻夸克系统联系起来，为强相互作用理论、量子色动力学（QCD）建立基准，处于中间状态。具有两个奇怪夸克的级联重子组合在双夸克系统中，预计其行为与重轻介子非常相似。阿斯利的分析将验证这一假设的有效性。我们期望她的工作能够成为一篇非常有影响力的论文。 Asli将分析2019-2022年收集的CLAS-12数据，同时对其进行充分校准和烹调。她的项目的某些部分将集中于模拟CLAS-12环境中的各种反应以及利用人工智能元素进行理论数据处理。
