Theoretical Studies in QCD, Electroweak and non Standard Model Physics

这个提议涵盖了一系列的主题，从天体物理学到QCD对撞机物理学，再到标准模型之外的物理学。 PI建议研究中微子与外部磁场的相互作用，高能中微子-核子相互作用和暗能量的非标准模型。 这些过程对于超新星和高能中微子天文学实验都很重要。 我们将研究正电子素衰变的非对易几何的实验结果。 几个重要的过程，如生产的希格斯玻色子和双光子，以及生产的重夸克对撞机物理将使用下一个到下一个领先的阶微扰理论QCD以及再确认计划进行研究。还将研究一种计算LHC预期的多喷流事件速率的方案。

This proposal covers a spectrum of topics, ranging from astrophysics, to QCD collider physics, to physics beyond the Standard Model. The PI's propose to study neutrino interactions with external magnetic fields, ultrahigh energy neutrino-nucleon interactions and non-standard models of dark energy. These processes are important for supernova and for high-energy neutrino astronomy experiments. Experimental consequences of noncommutative geometry for positronium decay will be investigated. Several processes important to collider physics such as the production of the Higgs boson and di-photons as well as the production of heavy quarks will be studied using next to next to leading order perturbation theory in QCD as well as resummation schemes. A scheme for calculating rates for multi jet events expected at LHC will also be investigated.
