CAREER: Parity-Violating Electron Scattering and Rare Kaon Decay

这一职业奖项将支持一个为期四年的研究和教学活动计划。这项研究将解决奇异夸克海对低能核子性质的贡献和CP破坏的来源等问题。奇特的夸克海贡献将用极化电子从原子核上的破坏宇称的电子散射来测量。实验将在麻省理工学院-贝茨直线加速器中心(质子和氚)和托马斯·杰斐逊国家加速器中心(氦原子核)进行。这些实验将确定奇怪的夸克海对质子的磁矩和电形状因数的贡献。布鲁克海文国家实验室将通过测量一种罕见的克子衰变的分支比来探索CP破坏的来源。这项提议的教学方面包括使用数学符号处理软件开发学习模块，并将其纳入本科高级水平的几个物理课堂。博士后研究员和研究生将通过对该奖项资助的研究项目的积极贡献来进行教育。

This CAREER award will support a four year program of research and teaching activities. The research will address the issues of the contribution of the strange quark sea to low energy nucleon properties and the origin of CP violation. The strange quark sea contributions will be measured using parity-violating electron scattering of polarized electrons from nuclei. Experiments will be carried out at the MIT-Bates Linear Accelerator Center (on the proton and deuteron) and at the Thomas Jefferson National Accelerator Center (on the helium nucleus). These experiments will result in a determination of the strange quark sea contribution to the magnetic moment and electric form factor of the proton. The origin of CP violation will be probed through the measurement of the branching ratio of a rare kaon decay to be carried out at the Brookhaven National Laboratory. The teaching aspect of this proposal includes the development and incorporation of learning modules using mathematical symbolic manipulation software into several physics classes at the advanced undergraduate level. Postdoctoral fellows and graduate students will be educated through active contribution to the research projects funded by this award.
