Standard Model Predictions for Physics at High Energy Colliders

标准模型用规范理论描述基本粒子的相互作用：强相互作用的量子色动力学(QCD)和与实验相符的Glasow-Weinberg-Salam。然而，这并不能自然地解释粒子质量谱、弱电性规范对称性的破坏，或者QCD和GWS耦合的不同强度：这些缺陷强烈地表明希格斯粒子的存在，以及在不久的将来可能出现的能量下的新相互作用。微扰理论是一种级数展开，可以用来研究高能QCD。然而，展开参数并不小，高阶修正是实质性的。这些修正将针对各种轻子和强子反应进行计算，以获得横截面归一化、横向动量和其他分布的可靠预测。这些预测将允许对QCD进行更精确的测试；它们将有助于研究由于初始态强子和强子喷注中强大的夸克-胶子力而产生的非微扰效应；它们将有助于明确识别电弱信号和可能的新相互作用。将研究GWS规范玻色子和希格斯玻色子的产生：信号将与QCD背景进行比较，并将识别显示背景不共享的属性(如宇称破坏)的不寻常信号。这些结果将由一位非常受人尊敬和有能力的基本粒子理论家获得，将使标准模型的精确测试能够在目前运行或正在建设的加速器上进行，并将有助于设计和执行在未来的超级对撞机上寻找新粒子和相互作用的实验。

The Standard Model describes elementary particle interactions in terms of gauge theories: Quantumchromodynamics (QCD) for the strong interactions and the Glashow-Weinberg- Salam agreement with experiment. However, it does not naturally explain the particle mass spectrum, the breaking of electroweak gauge symmetry, or the different strengths of the QCD and GWS couplings: these deficiencies strongly indicate the existence of a Higgs particle and possible new interactions at energies which will become available in the near future. Perturbation theory, a power series expansion, may be used to study QCD at high energies. However, the expansion parameter is not small and higher-order corrections are substantial. These corrections will be computed for various lepton and hadron reactions to obtain reliable predictions of cross section normalizations, and transverse momentum and other distributions. These predictions will allow for more precise tests of QCD; they will aid in studying non-perturbative effects due to strong quark-gluon forces in initial-state hadrons and in hadron jets; and they will facilitate unambiguous identification of signals of the electroweak and possible new interactions. Production of GWS gauge bosons and of the Higgs boson will be studied: signals will be compared with QCD backgrounds, and unusual signals which exhibit properties, such as parity-violation, that are not shared by the background will be identified. These results, to be obtained by a very highly-regarded and capable elementary particle theorist, will enable precision tests of the Standard Model to be made at accelerators presently in operation or under construction, and will aid in the design and execution of experiments searching for new particles and interactions at future super colliders.
