Development of Trigger Systems for the Higgs Search by the Dzero Experiment

这项核磁共振成像提案要求为几个大学小组提供支持，以开发用于触发费米实验室Tevatron反质子-质子对撞机D0实验的新组件。该装置处于实验粒子物理的能量前沿。该实验的主要目标是寻找希格斯玻色子，这是希格斯场的物理表现。在粒子物理的标准模型中，希格斯场提供了一种产生粒子质量并自发打破电弱相互作用对称性的方法。有许多迹象表明，Tevatron对撞机可以产生希格斯玻色子，只要提供足够的反质子-质子碰撞到实验中。计划中的Tevatron亮度升级将要求实验比过去更具选择性，因此高效的触发系统至关重要。背景抑制因子大于105的选择算法必须高效率地实时实现。这项提议将支持开发D0实验所需的硬件和算法，以应对在升级后的亮度下产生的更高的相互作用速率。

This MRI proposal requests support for several university groups for the development of new components for the trigger of the D0 experiment at the Fermilab Tevatron antiproton-proton collider. This facility is at the energy frontier of experimental particle physics. The primary goal of the experiment is to search for the Higgs boson, the physical manifestation of the Higgs field. Within the Standard Model of particle physics, the Higgs field provides a means of generating the particle masses and spontaneously breaking the symmetry of the electroweak interaction. There are many indications that the Tevatron collider could produce the Higgs boson, provided that enough antiproton-proton collisions are delivered to the experiments. The planned luminosity upgrade of the Tevatron will require the experiments to be even more selective than in the past and thus an efficient trigger system is essential. Selection algorithms giving background rejection factors of more than 105 with high efficiency must be implemented in real time. This proposal would support the development of the hardware and algorithms necessary for the D0 experiment to cope with the higher interaction rates produced at the upgraded luminosities.
