研究成果名稱(中):噴流次結構的量子色動力學重求和方法
研究成果名稱(英):QCD resummation for jet substructures
簡要記述(中):本所研究員李湘楠博士與密西根州立大學研究人員合作,以微擾量子色動力學的重求和(resummation)方法為基礎,建立強子對撞機中噴流(jet)現象的理論架構,成功描述費米實驗室及大型強子對撞機測量的噴流質量與噴流內部的能量分佈。噴流的測量是高能實驗物理學家用以辨識對撞機生成粒子(包括新粒子)的主要方法,之前對於這些觀測量的預測必須依賴數值模擬,李湘楠博士的工作首度實現物理學家以量子場論研究噴流現象的想法,此最新研究成果已發表於《物理評論通訊(Physical Review Letters)》。
簡要記述(英):Dr. Hsiang-nan Li developed a theoretical framework for studying jet observables through a collaboration with researchers of Michigan State University, which is based on the perturbative QCD resummation. Using this framework, they have successfully explained jet distributions in invariant mass and jet energy profiles measured by Fermilab and Large Hadron Collider. Jet observables have been used to identfy particles produced at hadron colliders, whose predictions always rely on Event Generators. Dr. Li`s work realized the goal of studying these observables using Quantum Field Theory for the first time. This new development has been published in Physical Review Letters.

研究成果名稱(中):B介子雙體非輕子衰變的理論
研究成果名稱(英):Theory for two-body nonleptonic B meson decays
簡要記述(中):雙體非輕子衰變是近年來B物理領域中最重要的課題,此衰變的測量可決定標準模型中的基本參數,CKM(Cabibbo-Kobayashi-Maskawa)矩陣元,此矩陣元若為複數,其相角即為CP對稱性破壞的來源之一。然而,實驗數據並不直接與CKM矩陣元關聯,所有強子過程皆包含量子色動力學(QCD)的機制,此機制的非微擾性使以上的關聯益形複雜。發展B介子衰變的QCD理論乃成為B物理理論界最迫切的任務。本人於2000年提出研究B介子雙體非輕子衰變的理論,以微擾量子色動力學(PQCD)為基礎,具有預測能力。許多PQCD的預測都獲得實驗的證實,譬如本人在2001年預測 B -> K pi 中的CP破缺約為 -10%,後來獲得史旦福大學的線性加速器中心(SLAC)和日本的高能加速器研究機構(KEK)B工廠(分別稱為BABAR和BELLE)的證實。PQCD已成為B物理領域的主要QCD理論。
簡要記述(英):Two-body nonleptonic B meson decays are one of the most important subjects in B physics, whose measurements can be used to determine the fundamental parameters, the CKM (Cabibbo-Kobayashi-Maskawa) matrix elements, in the Standard Model. If these matrix elements are complex, their phases will be one of the sources of CP violation in the universe. However, experimental data are not directly related to the CKM matrix elements. All hadronic processes involve mechanism from Quantum Chromodynamics (QCD), whose nonperturbative origin further complicates the relation. Developing a QCD theory for B meson decays became a urgent task in the theoretical community of B physics. We proposed a theory for the study of two-body nonleptonic B meson decays based on perturbative QCD (PQCD) in 2001, which has strong predictive power. Many PQCD predictions have been confirmed by experiments. For example, we predicted the direct CP asymmetry in decays to be -10% in 2001, that was confirmed by the B factories at the SLAC National Accelerator Laboratory in USA and at KEK in Japan, which are called BABAR and Belle, respectively. PQCD has become one of the major QCD theories in B physics.
