| dc.description.abstract | 本篇論文呈現了由新理論模型預測之粒子衰變到一個希格斯粒子和一個 Z 玻色子的分析。本分析使用了於 2015 年由大強子對撞機中的緊湊渺子線圈偵測器所記錄之質子-質子對撞總能量為 13 TeV，總亮度為 2.5 fb-1 的數據。高動量的希格斯粒子衰變到一個底夸克和一個反底夸克，在偵測器裡被偵測為一個大質量的噴流。Z 玻色子有兩個衰變通道，分別為正反電子通道以及正反渺子通道。本分析將分別探討電子通道和渺子通道，各通道將再細分為單底夸克標記和雙底夸克標記此二類別。通過合併電子通道和渺子通道，以及它們所有的底夸克標記類別，結果顯示質量由 800 GeV 至 4000 GeV 的新粒子於 95%信置區間的生產截面上限為 0.063 pb 至0.265 pb。 | zh_TW |
| dc.description.abstract | A search for heavy resonances decaying to a Higgs boson and a Z boson is presented. The analysis is based on the data collected in 2015 with the CMS detector at a center-of-mass energy √s = 13 TeV, corresponding to an integrated luminosity of 2.51 fb-1. The Higgs bosons are reconstructed from high momentum bb quark pairs that are detected as a single massive jet, while the Z bosons are reconstructed from electron pairs and muon pairs. The analysis is separated in electron and muon channels, with single and double b-tag categories. A 95% upper limit on the production cross section of σX × B(X → ZH) is derived from the combination of four categories with a limit of 0.063 pb to 0.265 pb for mX from 800 to 4000 GeV. | en_US |
