十年了! 大強子對撞機至今已經運行了十年並且成功提供兩輪的對撞實驗擷取。CMS實驗至今已擷取約150/fb的實驗數據並且產出超過800篇期刊論文。台灣CMS團隊(台大高能物理組與中大高能物理組)自1999年開始參與CMS實驗以來，無論在探測器建造或是物理分析上皆對CMS實驗作出許多重要貢獻。雖然台灣團隊人數僅佔整個實驗約1%，然而我們的貢獻，包括物理分析，已遠超過這個比例。從2024年到2026年中，CMS實驗將升級數個探測器以面對大強對撞機在高亮度對撞下的挑戰。這也是所謂的第二階段升級計畫。CMS實驗目前運轉中的兩端電磁和強子量能器將被高粒度量能器取代，這個新的量能器將會是高能物理實驗史上以矽偵測器建造最大型的量能探測器。我們提議台灣團隊參與此探測器升級計畫，並更進一步提升我們在CMS實驗中的能見度。 ;Ten years! It has been ten years since the start of operations of Large Hadron Collider (LHC) at CERN. LHC made two successful runs. The CMS experiment collected about 150/fb of data and submitted more than 800 scientific papers to the journals. The Taiwan CMS teams, NTUHEP and NCUHEP, has significantly contributed to the construction of detectors and the physics harvest in the LHC since 1999. Although the number of participants from Taiwan is just about 1% of CMS members, our contributions, including the physics publications, to CMS is much more than this fraction. From 2024 to mid-2026, CMS will install several new detectors to provide the necessary physics performance under the challenging of high luminosity at the LHC. This is the so-called phase-2 upgrade project. The electromagnetic and hadronic endcap calorimeters in CMS will be replaced with the high granularity calorimeter (HGCal), which will be the largest silicon-based calorimeter every built. We propose Taiwan teams to involve in CMS HGCal upgrade and increase our visibility in CMS.
