This U.S.-Mexico award will support Professor Sandip Pakvasa and a group of theoretical physicists from the University of Hawaii in Manoa and the University of Massachusetts at Amherst, in collaboration with a group of physicists at the Mexican Centro de Investigacion y de Estudios Avanzados (CINVESTAV). The objective of the proposed research is to study various fundamental questions concerning the standard model of electro-weak interactions. In particular, the group plans to investigate radiative corrections in the standard model, calculate decay rates, polarization effects, and branching ratios in the non-leptonic decays of baryions, pursue theoretical and phenomenological studies of CP violation, and study models for Fermion masses and mixings and their implications for collider physics. This research cooperation will unite leading researchers in the U.S., with considerable experimental expertise at colliding beam and non-accelerator physics facilities, with one of the strongest theoretical groups in Mexico in the area of unified models. The proposed collaboration will serve to enhance interactions between these active groups and promote the training of graduate students.

这项美国-墨西哥奖将支持Sandip Pakvasa教授和一组来自夏威夷大学马诺亚分校和马萨诸塞大学阿默斯特分校的理论物理学家，以及墨西哥研究中心（CINVESTAV）的一组物理学家的合作。提出的研究目的是研究有关电弱相互作用标准模型的各种基本问题。特别是，该小组计划研究标准模型中的辐射修正，计算重子的非轻子衰变中的衰变率，极化效应和分支比，进行CP违反的理论和现象学研究。研究费米子质量和混合的模型以及它们对对撞机物理的影响。这项研究合作将联合美国在对撞束和非加速器物理设施方面拥有大量实验专业知识的领先研究人员，以及墨西哥在统一模型领域最强大的理论团体之一。拟议的合作将有助于加强这些活跃团体之间的相互作用，并促进研究生的培训。
