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 在量子场论和量子色动力学（QCD）的具体方面和电弱物理的标准模型的一些理论研究将进行。 所采用的方法大多是非微扰的，包括格点QCD中的Monte Carlo模拟，微扰理论的解析改进和1/N展开。 晶格计算将导致高精度的衰变常数和质量分裂的B介子系统的第一原理评估，在B-工厂的B-介子现象学即将到来的研究的核心重要性。 非微扰技术对于解决强耦合场论（如QCD）中的问题至关重要。 攻击的问题代表了量子场论中热门的基本问题，以及与当前和未来几代粒子加速器直接现象学相关的问题。 ***
