Theoretical Studies in QCD, Electroweak and non Standard Model Physics

该提案涵盖了一系列主题，从天体物理学到QCD对撞机物理学，再到超越标准模型的物理学。PI提议研究中微子与外部磁场的相互作用，超高能量中微子-核子相互作用以及暗能量的非标准模型。这些过程对超新星和高能中微子天文学实验都很重要。非交换几何对正电子衰变的实验结果将被研究。一些对撞机物理的重要过程，如希格斯玻色子和双光子的产生，以及重夸克的产生，将在QCD和恢复方案中使用相邻的阶摄动理论进行研究。本文还将研究一种计算大型强子对撞机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.
