西元年：2009 研究人員(中)：阮自強、張嘉俊、李重生、高俊、張昊、李钊、袁展鵬、阮自強 研究人員(英)：YUAN, TZU-CHIANG, Jia Jun Zhang,Chong Sheng Li,Jun Gao,Hao Zhang,Zhao Li,C.-P. Yuan,Tzu-Chiang Yuan 研究成果名稱(中)：關於頂夸克與模型無關風味改變的中性流耦合常數之量子色彩動力學的次領階修正 研究成果名稱(英)：Next-to-Leading-Order QCD Corrections to the Top-Quark Decay via Model-Independent Flavor-Changing Neutral-Current Couplings 簡要記述(中)：在費米實驗室最近的 D0 和ＣＤＦ實驗，找尋了單獨頂夸克在非標準模型中的可能產生過程; 從測量到的總散射截面，加上其在強作用中的次領階修正計算，得到關於反常頂夸克風味改變的中性流耦合常數的上限。我們的工作，發表於2009年的物理評論通 (Phys. Rev. Lett. 102, 072001, 2009) ，主要是計算頂夸克這些反常耦合常數在強作用下的次領階修正，以及其對頂夸克各種衰變率的效應。我們指出了，此結果不僅在 D0 和ＣＤＦ實驗由反常耦合引致單獨頂夸克的產生與衰變，基於自身相容性一定要考慮到 ; 同時對 LHC 的 ATLAS 和 CMS 實驗是否能測量到這些反常耦合的靈敏度也至關重要。我們發現，與領階計算的成果比較，其強作用次領階修正對以下三個頂夸克衰變 , 和 的衰變率之大小改變約為10%，而其分率改變分別是20%，0.4% 和 2%。 簡要記述(英)：D0 and CDF collaborations at the Fermilab Tevatron have searched for non-standard-model single top-quark production and set upper limits on the anomalous top quark flavor-changing neutral current (FCNC) couplings and using the measurement of total cross section calculated at the next-to-leading order (NLO) in QCD. In this Letter, we report on the effect of anomalous FCNC couplings to various decay branching ratios of the top quark, calculated at the NLO. This result is not only mandatory for a consistent treatment of both the top quark production and decay via FCNC couplings by D0 and CDF at the Tevatron but is also important for the study of ATLAS and CMS sensitivity to these anomalous couplings at the CERN LHC. We find that the NLO corrections to the partial decay widths of the three decay channels , and are at the order of 10\% in magnitude and modify their branching ratios by about 20\%, 0.4\% and 2\%, respectively, as compared to their leading order predictions. 主要相關著作： Jia Jun Zhang, Chong Sheng Li, Jun Gao, Hao Zhang, Zhao Li, C.-P.
