This proposal centers on determining precision tests of the Standard Model of particle physics and new physics beyond the Standard Model at present and future collider facilities. The PI proposes to do a full one-loop computation of neutrino-nucleon scattering. This is the essential missing ingredient that is needed to understand whether the recently observed NuTeV anomaly is in fact a deviation from the Standard Model or just a consequence of higher order radiative effects The PI proposes a variety of calculations covering radiative corrections to electroweak observables (mainly WW production), radiative corrections to both Higgs boson production and decay processes, top quark production, neutrino deep inelastic scattering and precision measurements of SUSY processes at a future linear collider.

该提案的重点是确定粒子物理学标准模型和超越标准模型的新物理学在目前和未来的对撞机设施的精度测试。PI建议对中微子-核子散射进行完整的单循环计算。这是需要了解最近观察到的NuTeV异常实际上是否偏离标准模型或只是高阶辐射效应的结果的基本缺失成分。PI提出了各种计算，包括对电弱可观测量的辐射校正。（主要是WW产生），对希格斯玻色子产生和衰变过程的辐射修正，顶夸克产生，中微子深度非弹性散射和精确测量超对称过程在未来的线性对撞机。
