研究方向

對撞機唯象學,超出標準模型的新物理,精確計算,有效場論正定性

研究內容與成就

從事大型強子對撞機 (Large Hadron Collider)上頂夸克和希格斯粒子唯象學的研究,具體包括:使用模型無關的理論框架——即標準模型的有效場論(Standard Model Effective Field Theory)——研究TeV新物理和對撞機唯象學;開發實驗分析需要的高精度事件產生子(event generator)程式;正定性約束在標準模型有效場論中的套用。這些工作為人們在對撞機上尋找TeV能區的新物理粒子和新物理規律提供了理論支持和計算工具。
主要研究成就包括:發展了以有效場論作為框架研究超出標準模型的頂夸克物理和電弱物理的模型無關的方法;通過在MadGraph5_aMC@NLO框架中實現自動化計算,將基於有效場論的頂夸克物理精準唯象研究系統地推進到了次領頭階精度;提出了約束力最強的多場領頭階正定性約束及其高效的求解方法,並利用這些約束大大縮減了標準模型有效場論的物理參數空間,闡釋了正定性約束對確定紫外高能粒子態的重要性;提出了利用衰變產物中的底夸克電荷不對稱性的運動學信息,在高亮度條件下測量頂夸克寬度的新方法。
已在Physical Review Letters, Journal of High Energy Physics等國際頂級或重要專業期刊發表學術論文40餘篇,論文的總引用率超過了2500次,是國內標準模型有效場論及其在大型強子對撞機套用上的青年領軍人物,在國際上具有重要的學術地位和影響力。擔任國際有效場論系列線上講座“All Things EFT”核心組織者,以及希格斯玻色子系列會議國際組織委員會委員。
