Research in Particle Physics with ATLAS at the LHC

ATLAS(环面大角度光谱仪)是一个通用探测器，旨在开发大型强子对撞机质子-质子对撞机的潜力。这是一个由来自31个国家的145个研究所的1500名科学家组成的国际合作组织，其中包括来自28个美国机构的250名物理学家。汉普顿大学正在参与该探测器的建造工作，负责组装“跃迁辐射跟踪器”。大型强子对撞机将提供比以往对撞机高10倍的质心能量和10-100倍的质子-质子碰撞率，从而开辟了物理学的新前沿。发现质量产生机制(通过涉及希格斯玻色子的“自发对称性破缺”)是ATLAS的主要目标。此外，理论发展表明，物质的构成要素和基本相互作用可能存在一个更一般的框架(称为“超对称”)，这预示着一类新基本粒子的存在。发现这种“超对称粒子”是另一个目标。该项目由OMA/MPS和EPP/PHY提供资金。

ATLAS (A Toroidal Large Angle Spectrometer) is a general-purpose detector that is designed to exploit the potential of the LHC proton-proton collider. It is an international collaboration of 1500 scientists, from145 institutes in 31 countries, including 250 physicists from 28 US institutions. Hampton University is participating in the construction of this detector with responsibilities for assembling the "Transition Radiation Tracker". The LHC will provide 10 times higher center-of-mass energy and 10-100 times higher proton-proton collision rates than previous colliders, thus opening up a new frontier of physics. Discovery of the mass-generating mechanism (via "spontaneous symmetry breaking" involving the Higgs boson) is a primary objective of ATLAS. In addition, theoretical developments indicate the possible existence of a more general framework (called "supersymmetry") for the building blocks of matter and the fundamental interactions, which predicts the existence of a new class of fundamental particles. The discovery of such "supersymmetric particles" is another goal. This project is funded by the OMA/MPS and EPP/PHY.
