U.S.-Mexico Cooperative Research Project for Experimental Particle Physics

9600342美国项目奖将支持威斯康星大学的Marleigh Sheaff博士、科罗拉多大学的John Cumalat教授、墨西哥CINVESTAV-IPN的Hector Mendez教授和Gerardo Herrera教授在实验基本粒子物理方面的合作研究。具体地说，研究人员打算集中精力在费米实验室进行魅力光产生实验(E831)，以便对各种魅力介子和重子态进行高精度研究。研究人员打算对魅力重子的寿命和其他性质进行系统研究，并将致力于对现有的宽带光子实验室光谱仪进行升级，这将显著扩大E831实验的物理范围。在采集数据和分析收集的数据期间维护探测器的责任将由双方共同承担。该项目将有助于大型科学项目的国际化；它对学生参与的重视将有助于促进未来的合作。***

9600342 Sheaff This Americas Program award will support collaborative research between Dr. Marleigh Sheaff of the University of Wisconsin, Professor John Cumalat of the University of Colorado, Professor Hector Mendez and Professor Gerardo Herrera of CINVESTAV-IPN in Mexico, in experimental elementary particle physics. Specifically, the researchers intend to concentrate on a charm photoproduction experiment (E831) to be performed at Fermilab, in order to conduct high precision studies of varied charmed meson and baryon states. The researchers intend to conduct a systematic study of the lifetimes and other properties of charmed baryons and will work on upgrades to the existing Wide Band Photon Lab Spectrometer that will significantly extend the physics reach of the E831 experiment. Responsibility for maintaining the detectors during data taking and the analysis of the collected data will be shared by both sides. The project will contribute to the internationalization of large science projects; its emphasis on student involvement will help to promote future collaborations. ***
