This award supports research in connection with experiments in meson spectroscopy. The primary effort is directed at the RadPhi experiment, which aims to measure the radiative decays of the phi(1020) meson toscalar states a0(980) and f0(980) in phi photoproduction. Theexperiment has collected its data during a 60-day run in summer 2000,and is in the final stages of data analysis. The P.I. is spokesman ofRadphi. In addition to radiative decays, the Radphi data also contain anumber of all-neutral final states in photoproduction at 5 GeV, whichare being studied using partial-wave analysis. These studies are asignificant contribution to preparations for the GlueX experiment, whichundertakes a comprehensive analysis of both charged and neutral finalstates in photoproduction at 9 GeV. Within the GlueX experiment, theUConn group has responsibility for the coherent photon source andtagger, and for physics simulations.

该奖项支持与介子光谱学实验有关的研究。 主要工作是针对RadPhi实验，其目的是测量phi光生过程中phi（1020）介子到标量态a0（980）和f0（980）的辐射衰变。 该实验在2000年夏季进行了60天的运行，收集了数据，并在数据分析的最后阶段。 私家侦探是Radphi的发言人 除了辐射衰变，Radphi数据还包含了一些在5 GeV的光生过程中的全中性末态，这些末态正在使用分波分析进行研究。 这些研究是一个重大的贡献，准备的GREX实验，其中承担了全面的分析，在9 GeV的光产生的带电和中性的finalstates。 在GSTX实验中，康州大学团队负责相干光子源和标记器，以及物理模拟。
