论文摘要
Beam Recoil转移了$ k^+λ$的独家电源的极化,并使用杰斐逊实验室的CLAS12光谱仪测量了来自非极化质子目标的最终状态。光束能量的测量值为6.535〜GEV和7.546〜GEV跨越了四摩诺特姆传输$ q^2 $从0.3到4.5〜GEV $^2 $,而不变的能量$ W $从1.6到2.4〜GEV,同时覆盖了$ k^+$的完整质量中心范围。这些新数据将现有的超子极化数据从CLAS扩展到类似的运动学范围,但从明显更大的数据集扩展了。它们代表了世界数据的重要补充,可以更好地探索陌生生产过程中的反应机理,以进一步了解激发核子状态的光谱和结构,并改善对非扰动动力学制度中强相互作用的洞察力。
Beam-recoil transferred polarizations for the exclusive electroproduction of $K^+Λ$ and $K^+Σ^0$ final states from an unpolarized proton target have been measured using the CLAS12 spectrometer at Jefferson Laboratory. The measurements at beam energies of 6.535~GeV and 7.546~GeV span the range of four-momentum transfer $Q^2$ from 0.3 to 4.5~GeV$^2$ and invariant energy $W$ from 1.6 to 2.4~GeV, while covering the full center-of-mass angular range of the $K^+$. These new data extend the existing hyperon polarization data from CLAS in a similar kinematic range but from a significantly larger dataset. They represent an important addition to the world data, allowing for better exploration of the reaction mechanism in strangeness production processes, for further understanding of the spectrum and structure of excited nucleon states, and for improved insight into the strong interaction in the regime of non-perturbative dynamics.
