Spin Symmetry for Anti-Lambda Spectrum in atomic nucleus
Chunyan Song, Jiangming Yao, and Jie Meng
TL;DR
This paper investigates the spin symmetry of the anti-Lambda spectrum in nucleus 16O using relativistic mean field theory, revealing very small spin-orbit splittings and near-identical Dirac spinor components, indicating strong spin symmetry.
Contribution
It provides the first detailed analysis of anti-Lambda spin symmetry in nuclei, showing it is better than that of anti-nucleons, based on relativistic mean field calculations.
Findings
Spin-orbit splittings are around 0.03-0.07 MeV.
Dirac spinor components are nearly identical for spin doublets.
Anti-Lambda exhibits stronger spin symmetry than anti-nucleons.
Abstract
The spin symmetry of anti-Lambda spectrum in nucleus O has been studied in the relativistic mean field theory. The spin-orbit splittings of spin doublets are found to be around 0.03-0.07 MeV and the dominant components of the Dirac spinor for the anti-Lambda spin doublets are found to be near identical. It indicates that there is an even better spin symmetry in the anti-Lambda spectrum than that in the anti-nucleon spectrum.
