9807009CotanchThis three-year award supports US-Portuguese collaborative research in the area of hadronic physics between Stephen Cotanch and Eric Swanson of North Carolina State University and Jose Ribeiro of the Instituto Superior Tecnico, Lisbon. The objectives of their research are to study problems in Quantum Chromodynamics (QDC) related to the structure of mesons and baryons, and to determine experimental signatures for glueballs, hybrid mesons, and the strangeness content of the nucleon. The project will combine an effective, field theoretical Hamiltonian from QCD combined with phenomenological insights derived from chiral symmetry. It will incorporate precise, new experimental information from the Jefferson National Accelerator Facility and Brookhaven National Laboratory.The US investigators and their students bring to this collaboration strengths in many-body and field theory and phenomenology. This is complemented by the Portuguese calculational expertise and an extension of their meson-baryon codes to accommodate an improved theoretical treatment and a focus on the implications of chiral symmetry.

9807009 Cotanchthis Tire三年奖奖支持北卡罗来纳州立大学Stephen Cotanch和北卡罗来纳州立大学的Eric Swanson和北卡罗来纳州立大学的Eric Swanson和里斯本北卡罗来纳州立大学的Eric Ribeiro之间的美国 - 葡萄牙合作研究。 他们的研究的目标是研究与介子和重子的结构有关的量子染色体动力学（QDC），并确定胶球，杂交介子和核子的陌生含量的实验特征。 该项目将结合QCD的有效的，田间理论上的哈密顿量，并结合手性对称性的现象学见解。 它将结合杰斐逊国家加速器设施和布鲁克黑文国家实验室的精确，新的实验信息。 葡萄牙的计算专业知识以及其介子 - 巴里昂代码的扩展，以适应改进的理论处理，并重点关注手性对称性的含义，这补充了这一点。
