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。重点将放在探测理解电弱对称性破缺，产生质量的W和Z玻色子以及夸克。 PI建议理解末态相互作用对测量顶夸克-底夸克和W玻色子之间耦合的影响。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。在标准模型中，将对LHC中W和Z玻色子的成对产生进行预测，可以与由于额外维度而产生的奇异机制进行比较。PI还打算研究中微子质量对标准模型超对称扩展现象学的影响。
