核子-核子弹性散射数据的分波分析

Partial-Wave Analysis of Nucleon-Nucleon Elastic Scattering Data

Ron L. Workman, William J. Briscoe, Igor I. Strakovsky

摘要:

与现有核子-核子数据库的能量相关和单能量拟合已经更新,以纳入最近的测量结果。拟合覆盖了从阈值到3 GeV的区域,在实验室动能中,质子-质子散射,中子-质子散射的上限为1.3 GeV。在COSY-WASA和COSY-ANKE设施进行的实验对分波解产生了重大影响。结果进行了讨论的分波和直接重建振幅。

英文摘要:

Energy-dependent and single-energy fits to the existing nucleon-nucleon database have been updated to incorporate recent measurements. The fits cover a region from threshold to 3 GeV, in the laboratory kinetic energy, for proton-proton scattering, with an upper limit of 1.3 GeV for neutron-proton scattering. Experiments carried out at the COSY-WASA and COSY-ANKE facilities have had a significant impact on the partial-wave solutions. Results are discussed in terms of both partial-wave and direct reconstruction amplitudes.
