9322114 Duncan A number of theoretical investigations in Quantum Field Theory and specific aspects of Quantum Chromodynamics (QCD) and the Standard Model of Electroweak physics will be carried out. The methods employed will mostly be nonperturbative, including Monte Carlo simulations in lattice QCD, analytic improvement of perturbation theory, and 1/N expansions. The lattice calculations will lead to high-precision first-principle evaluations of decay constants and mass splittings in the B-meson system, of central importance for upcoming studies of B-meson phenomenology in B-factories. Nonperturbative techniques are essential for attacking problems in strongly-coupled field- theories such as QCD. The problems attacked represent fundamental issues of topical interest in Quantum Field Theory and matters of direct phenomenological relevance to current and future generations of particle accelerators. ***

9322114邓肯（Duncan）将在量子场理论和量子染色体动力学（QCD）的特定方面进行许多理论研究，并将进行电子电动物理学的标准模型。 所采用的方法主要是非扰动的，包括晶格QCD中的蒙特卡洛模拟，扰动理论的分析改进和1/N扩展。 晶格计算将导致B-Meson系统中对衰减常数和质量分裂的高精度第一原则评估，这对于B-Meson现象学研究的核心重要性至关重要。 非扰动技术对于在诸如QCD之类的强耦合现场理论中攻击问题至关重要。 攻击的问题代表了量子场理论中主题兴趣的基本问题，以及与当前和后代粒子加速器的直接现象学相关性的问题。 ***
