An study on muon trigger at proton colliders with high luminosity

点击翻译按钮获取中文摘要

Based on analysis of 7TeV collision data at LHC, it is found that most of muon trigger in the endcap region are fake due to charged tracks produced near the troidal magnet. So, it is very important to prove that tracks are really come from the interaction point by requesting hits in the small wheel detectors. In addition, we have made basic design of trigger processors to provide trigger performance required.
