Searching for signals of Beyond Standard Model Physics at the Atlas detector of the Large Hadron Collider.

Atlas的运行每年产生pb级的数据，即将到来的“High Luminosity”升级将需要exabyte级的存储。迄今为止，粒子物理学的标准模型已被发现足以描述所有观察到的效应。然而，许多当前搜索的灵敏度并不受数据量的限制，而是受其在物理模型背景下精确解释的计算费用的限制——无论是探测器还是它所属的宇宙。该项目侧重于使用概率论来分析质子散射数据，首先关注的是被怀疑包括希格斯玻色子衰变为两个tau轻子的事件。衰变模型的无约束方面将通过蒙特卡罗与嵌套采样的集成被边缘化。

Operation of Atlas produces petabytes of data per year, and storage on the exabyte scale will be required for the upcoming "High Luminosity" upgrade. The Standard Model of particle physics has so far been found sufficient to describe all observed effects. However, the sensitivity of many current searches is not limited by data quantity, but by the computational expense of its accurate interpretation in the context of physical models - both of the detector and the universe of which it is a part. The project focuses on use of probability theory to analyse proton scattering data, beginning with a focus on events suspected to include the decay of a Higgs boson to two tau leptons. Unconstrained aspects of the decay model are to be marginalised through Monte Carlo integration with Nested Sampling.
