Experimental High Energy Physics and Development of a Calorimeter Level-2 Trigger for the DO Experiment

*9804320亚当斯这笔赠款将支持费米实验室Tevatron使用升级的DO探测器进行的研究。在泰瓦特龙，质子和反质子以目前世界上可用的最高能量相撞。实验人员还在帮助建造CMS探测器，该探测器将在大型强子对撞机(LHC)上获取数据。这台对撞机将在2005年左右从费米实验室手中接管能量前沿。这些对撞机上的碰撞产生了许多不同类型的粒子，可以通过研究它们在探测器中留下的信号来揭示这些粒子。实验人员研究这些信号，希望找到以前没有见过的新类型粒子的证据。希格斯粒子就是实验者正在寻找的这样一种粒子。对这种粒子的探测将有助于物理学家解释/理解粒子为什么有质量。实验者还可能找到超对称粒子的证据。

***9804320Adams This grant will support studies using the upgraded DO detector at the FERMILAB Tevatron. At the Tevatron protons and anti-protons are collided at the highest energies currently available in the world. The experimenters are also helping to construct the CMS detector which will take data at the Large Hadron Collider (LHC). This collider will take over the energy frontier from Fermilab around 2005. The collisions at these colliders produce many different types of particles which can be revealed by studying the signals they leave behind in the detectors. The experimenters study these signals in the hope of finding evidence of new types of particles not previously seen. The Higgs is one such particle which experimenters are looking for. The detection of this particle will help physicists to explain/understand why particles have mass. The experimenters may also find evidence for supersymmetric particles.***
