The student will conduct searches for SUSY particles with b-tagged jets at ATLAS, including searches for gluinos decaying via top squarks and bottom squarks decaying directly to the lightest SUSY particle. Later in the project the student will work on a new idea to improve ATLAS sensitivity to compressed SUSY scenarios using shape fits to exploit the universality of the squark/gluino effective mass distribution. The student will also work on validating and improving particle flow reconstruction in ATLAS, including both improvements to the existing particle flow jet reconstruction algorithm and the development of a new global particle flow paradigm. The student will also contribute to the calibration of b-tagged particle flow jets.

该学生将在ATLAS进行带有b-标记喷流的超对称粒子的搜索，包括通过顶部正方形和底部正方形直接衰变为最轻超对称粒子的胶子的搜索。在项目的后期，学生将研究一个新的想法，以提高ATLAS对压缩超对称性方案的灵敏度，使用形状拟合来利用夸克/胶子有效质量分布的普遍性。学生还将在ATLAS中验证和改进粒子流重建，包括对现有粒子流射流重建算法的改进和新的全局粒子流范例的开发。学生也将有助于b标记粒子流射流的校准。
