Prospects to study hyperon-nucleon interactions at BESIII
arxiv(2022)
摘要
The prospects to study hyperon-nuclei/nucleon interactions at BESIII and
similar e^+ e^- colliders are proposed in this work. Utilizing the large
quantity of hyperons produced by the decay of 10 billion J/ψ and 2.7
billion ψ(3686) collected at BESIII, the cross sections of several
specific elastic or inelastic hyperon-nuclei reactions can be measured via the
scattering between the hyperons and the nucleus in the dense objects of BESIII
detector. Subsequently, the cross sections of corresponding hyperon-nucleon
interactions are able to be extracted with further phenomenological
calculation. Furthermore, the interactions between antihyperon and
nuclei/nucleon, including scattering and annihilation, can also be studied via
the method proposed in this paper. The results will definitely benefit a lot
the precise probe of the hyperon-nuclei/nucleon interactions and provide
constraints for the studies of the potential of strong interaction, the origin
of color confinement, the unified model for baryon-baryon interactions, and the
internal structure of neutron stars. In addition, the desirable prospects of
corresponding studies in the future Super Tau-Charm Factory (STCF) are
discussed and estimated in this work.
