CLAS的奇异物理项目

The Strangeness Physics Program at CLAS

Daniel S. Carman

摘要:

一个广泛的计划,奇异粒子生产的核子目前正在进行与CEBAF大型接受光谱仪(CLAS)在大厅B在杰斐逊实验室。这次演讲将强调在W=1.6和2.4 GeV之间的重子共振区的奇异电产生,其中s-通道结构的迹象表明,高质量的重子共振耦合到最终状态的K介子和超子。精确测量的截面和偏振可观的进行高度极化的电子和真正的光子束的能量高达6 GeV。还将讨论该计划的近期和长期前景。

英文摘要:

An extensive program of strange particle production off the nucleon is currently underway with the CEBAF Large Acceptance Spectrometer (CLAS) in Hall B at Jefferson Laboratory. This talk will emphasize strangeness electroproduction in the baryon resonance region between W=1.6 and 2.4 GeV, where indications of s-channel structure are suggestive of high-mass baryon resonances coupling to kaons and hyperons in the final state. Precision measurements of cross sections and polarization observables are being carried out with highly polarized electron and real photon beams at energies up to 6 GeV. The near-term and longer-term future of this program will also be discussed.
