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 focus will be on probes for understanding for electro weak symmetry breaking which generates the mass for the W and Z bosons as well as for the quarks. The PI proposes to understand the effects of final state interactions on the measurement of the coupling between the top quark-bottom quark and the W boson. He intends to carry out higher order calculations in QCD in order to predict the transverse momentum distribution for the Higgs particle. Predictions will be made for the pair production of W and Z Bosons at LHC in the standard model that can be compared with exotic production mechanisms due to extra dimensions. The PI also intends to investigate the effect of neutrino masses on the phenomenology of Supersymmetric extensions of the Standard Model.

该建议集中在确定粒子物理和新物理学标准模型的精确测试之外，超出了目前和未来的对撞机设施。重点将放在理解电弱对称性破坏的探针上，该探针为W和Z玻璃物以及夸克产生质量。 PI建议了解最终状态相互作用对顶部夸克底夸克和W玻色子之间耦合的测量的影响。他打算在QCD中进行高阶计算，以预测希格斯粒子的横向动量分布。将在标准模型中对LHC上W和Z玻色子的一对生产进行预测，该生产可以与由于额外的尺寸而引起的外来生产机制进行比较。 PI还打算研究中微子质量对标准模型超对称扩展的现象学的影响。
