研究成果名稱(中):中研院物理所參與歐洲物理實驗 證實上帝粒子衰變為底夸克
研究成果名稱(英):Observation of Higgs boson decays to bb at the LHC
簡要記述(中):今(2018)年8月28日,歐洲核子研究組織(CERN)的ATLAS 團隊宣布此實驗已觀察到希格斯玻色子確實會衰變成一對底夸克(H→bb),證實了一套粒子物理的預測。中央研究院物理所王嵩銘副研究員領導的團隊,對此次重大發現有關鍵貢獻。
在粒子物理的標準模型中,希格斯玻色子負責產生基本粒子的質量。標準模型預測希格斯玻色子約有60%的機率會衰變為成一對底夸克,因此,科學家致力於探索H→bb這個衰變過程,希望進一步檢驗這套質量產生機制。
然而,在大型強子對撞機裡,要觀察到希格斯玻色子衰變成底夸克便非常困難,需要相當長的時間佐以大量的數據樣本。 王嵩銘副研究員表示:「這次探索是大型強子對撞機中最具挑戰性的分析之一。」為實現目標,ATLAS團隊分析了前二次運行期間所收集的數據樣本,並採用多變量分析算法等先進的分析技術,成功將H→bb信號與背景的底夸克隔離。分析結果已在Physics Letter B期刊發佈。
簡要記述(英):After six years since the discovery of the Higgs boson through the decays into gauge bosons (photon, W, Z), the ATLAS and CMS experiments at the LHC have finally observed the Higgs boson decaying into a pair of b-quarks (H→bb), which accounts for the largest fraction (about 58%) of all possible decays. Both experiments jointly announced this observation at a CERN seminar on August 28th [1], which was followed by a press release [2]. This observation is very important as it further strengthen the understanding of the mass generation mechanism predicted in the Standard Model (SM), and provides an additional confirmation of the “Yukawa-couplings” in which the charged fermion particles (leptons, quarks) acquire masses through coupling with the Higgs boson. The Taiwan Academia Sinica (AS) group is part of the team that contributes to the ATLAS’ observation result.

At ATLAS the H→bb signal is observed with a significance of 5.4 standard deviations. This result is obtained through analyzing the ATLAS Run 1 and Run 2 data samples (total integrated luminosity of about 100 fb-1) with the application of advanced techniques to extract the tiny signal in the data. To detect the signal several of its properties are exploited to separate the signal from the background. For example the long lifetime of the b-hadrons in the jets of the b-quarks from the Higgs decay, and the invariant mass resonance form by the two-b-jet system (see Figure 1). It takes a considerably longer time and larger data sample to observe the Higgs boson in this decay channel due to the overwhelming b-quark pair background that is produced via the strong interaction at the LHC. Thus making this search one of the most challenging analyses at the LHC. The ATLAS preliminary observation result [3] was first presented at the 2018 International Conference on High Energy Physics (ICHEP) at Seoul in July [4]. A paper was submitted on the same day as the joint CERN seminar to the Physics Letter B journal for publication [5]. This significant result is the outcome of the dedicated work of many physicists of the ATLAS collaboration and the fantastic performance of the LHC machine. A more general public explanation of this significant result can be found at [6].

The AS group has been active in the Higgs boson search via the H→bb decay channel for many years starting in the CDF experiment at the Tevatron and later continued the search in the ATLAS experiment since the beginning of the data taking by ATLAS at the LHC. The data analysis effort by the AS group is led by associate research fellow Song-Ming Wang. The AS team, including also the post-doctorial research Adrian Buzatu and PhD student Wei Wang, contributed significantly to the “0-lepton” sub-channel of this search. In this sub-channel the Higgs boson is produced in association with a Z boson and that the Z boson decays into a pair of neutrinos. The contributions from the AS team include:
• Improving the resolution of the measured two-b-jet system mass,
• Measuring the performance of the trigger used to collect the data for the “0-lepton” channel,
• Training the multivariate analysis algorithm to separate the H→bb signal from background,
• Development of the analysis software and performing the analysis.
Comparing among the sub-channels for this H→bb search, the 0-lepton sub-channel has one of the best sensitivity. Song-Ming Wang had also served as a co-convener of the ATLAS Higgs H→bb working group in 2015-2016.

研究成果名稱(中):ATLAS實驗觀察到希格斯玻色子衰變到一對底夸克的證據
研究成果名稱(英):Evidence for Higgs decays to bb at ATLAS Experiment
簡要記述(中):希格斯玻色子(Higgs boson)在2012年被ATLAS和CMS實驗發現,當時的發現是透過規範玻色子衰變頻道。標準模型預測希格斯玻色子最常衰變為一對底夸克(H->bb,機率為~58%)。但是該頻道在LHC尚未被觀察到。 如果檢測到的H->bb衰變率與標準模型預測顯著不同則表示可能有新物理的跡象。
通過分析2015年和2016年收集的數據,ATLAS在希格斯玻色子與W或Z玻色子伴隨產生的模式中觀察到這種衰變 (H->bb) 模式的證據。這個證據的顯著性水平是3.5σ。為了檢測此搜索中的H->bb衰變,這個分析利用信號的幾個屬性將信號與背景分離。這個研究結過已發表在JHEP 12 (2017) 024 雜誌。 中央研究院(AS)於2011年加入ATLAS Hbb研究組,對微中子頻道(ZH->nunubb)作出了重大貢獻。該頻道是在這個搜索中使用的三個分析頻道之一。AS團隊一直積極參與此搜索。 AS-ATLAS團隊領導王嵩銘在2015-2016年擔任ATLAS Hbb研究組的聯合召集人。他也代表ATLAS實驗於2017/7/6在歐洲物理會議上首次公開了這項研究結果。
簡要記述(英):The Higgs boson was discovered in 2012 by the ATLAS and CMS experiments, in the gauge boson decay channels. Although according to the Standard Model (SM) Higgs decaying into a pair of b-quarks (H->bb) has the largest predicted decay branching fraction (BR~58%), this channel has not yet been observed at the LHC. If the detected H->bb decay rate differs significantly from the SM prediction, this could indicate a sign of new physics. Evidence of observing such decay mode was announced by ATLAS in July 2017, in the search channel where the Higgs boson is produced in association with a W or Z boson. To detect the H->bb decay in this search, several properties of the signal are exploited to separate the signal from the background. For example the long lifetime of the b hadrons in the jets of the b quark from the Higgs decay, and the invariant mass resonance form by the two-b-jet system. By analyzing the data sample collected with the ATLAS detector in 2015 and 2016, the first two years of LHC Run2 data taking, ATLAS found evidence for the H->bb decay at the significance level of 3.5 standard deviation. These results are published in JHEP 12 (2017) 024. Academia Sinica (AS) joined the ATLAS Hbb group in 2011 and made significant contributions to the neutrino decay channel (ZH->nunubb) that is characterized by large missing transverse energy. This channel is one of the three analyses channels employed in this evidence results. The AS group has continuously been an active participant in this search. Song-Ming Wang, leader of the AS-ATLAS team, had served as a co-convener of the ATLAS Hbb group in 2015-2016. He made the first public presentation of this evidence results on behalf of the ATLAS collaboration at the European Physical Society conference in Venice, Italy, on July 6th 2017.
