Research in Elementary Particle Theory (Physics)

在基本粒子物理的各种现象学和理论课题的研究将进行。计划进行两个涉及重夸克衰变的项目。首先，由于大QCD对衰变成希格斯玻色子的单环修正，计划在双希格斯双重态模型中计算希格斯玻色子对这一过程的单环修正（例如，在所有超对称理论中都需要）。其次，提出了重夸克衰变为Z和ZH的所有S态和p态的重新检验。并计划在强相互作用的电弱扇区中进行高能e -e碰撞中W和Z对产生的研究。我们将研究从超高能宇宙射线中微子相互作用中衍生出的轻夸克玻色子的质量和耦合的极限，以及由E推导的超弦激励模型的现象学。在更理论化的方面，基于（本作者和合作者）以前的研究，计划继续研究有限温度热浴对时空稳定性的影响。最后，还提出了两个涉及不破缺超对称理论性质的方案。一是研究超对称量子力学中的和规则及其与数学中特殊函数理论的关系。另一个将涉及各种横截面的单回路计算，以测试超对称理论中超过树水平的振幅零的存在。这项工作是由一位非常受尊敬的年轻理论物理学家完成的，它将增加我们对某些基本粒子的物理学的理解，这些基本粒子虽然迄今尚未被发现，但被广泛认为是存在的，并且是我们对自然基本力的理解的核心。

Research in a variety of phenomenological and theoretical topics in elementary particle physics will be carried out. Two projects involving heavy quarkonium decays are planned. First, motivated by the large QCD one-loop corrections to the decay into a Higgs boson, it is planned to calculate the one-loop corrections due to Higgs bosons to this process in two-Higgs doublet models (as required, for example, in all supersymmetric theories). Secondly, it is proposed that heavy quarkonium decays into Z and ZH final states be reexamined for all S- and P-states. It is also planned that the study of W and Z pair- production in high-energy e e collisions in the context of a strongly-interacting electroweak sector be udertaken. Limits on the masses and couplings of leptoquark bosons derivable from ultrahigh-energy cosmic ray neutrino interactions will be investigated as will the phenomenology of superstring-motivated models derived from E . On the more theoretical side, building on previous studies (of this author and collaborators), continued work on the effects of a finite-temperature heat bath on the stability of spacetime is planned. Finally, two projects involving properties of theories with unbroken supersymmetry are also proposed. One is the investigation of sum rules in supersymmetric quantum mechanics and their relation to special function theory in mathematics. The other will involve one-loop calculations of various cross-sections to test for the existence of amplitude zeros beyond tree level in supersymmetric theories. This work, by a very highly-regarded young theoretical physicist, will add to our understanding of the physics of certain elementary particles that, while so-far undiscovered, are widely believed to exist, and are central to our picture of the basic forces of nature.
