强子物理学与CLAS12

Hadron Physics with CLAS12

Stepan Stepanyan

摘要:

强子光谱学一直是物理学计划的重要组成部分,在杰斐逊实验室的实验大厅B的CLAS探测器。研究了高能(极化)电子束和光子束在从氢到铅的各种靶上产生重子和介子共振。感兴趣的物理主题包括:重子和介子共振谱的研究,跃迁形状因子,介子-核子耦合(原子核中的介子),以及寻找奇异和缺失的状态。随着CEBAF机器的12 GeV升级,大厅B的强子光谱学将扩展到一个更高质量共振的新领域,并使用高达11 GeV的电子束和升级后的CLAS 12探测器获得更高的转移动量。本文简要介绍了CLAS 12探测器和12 GeV的物理程序,重点介绍了重子和介子谱。

英文摘要:

Hadron spectroscopy has been an essential part of the physics program with the CLAS detector in experimental Hall B at Jefferson Lab. Production of baryon and meson resonances with high energy (polarized) electron and photon beams was studied on a veriety of targets, ranging from hydrogen to lead. Physics topics of interest include: investigation of the spectrum of baryon and meson resonances, transition form-factors, meson-nucleon couplings (mesons in nuclei), and search for exotic and missing states. With the 12 GeV upgrade of the CEBAF machine, hadron spectroscopy in Hall B will be extended to a new domain of higher mass resonances and the range of higher transferred momentum using up to 11 GeV electron beams and the upgraded CLAS12 detector. In this paper a brief description of the CLAS12 detector and the physics program adopted for 12 GeV with emphasis to baryon and meson spectroscopy is presented.
