Parallel session 29: Light and strange flavor physics & nuclei II
- Marcus Bleicher
With its precise vertex reconstruction and particle identification capabilities, the LHCb detector is ideally suited to study the production and polarization of strange particles. In addition, being the origin of hyperon polarization from unpolarized proton-proton and proton-nucleus collisions not yet fully understood, measurements in different collision systems and kinematic ranges must be...
Hadronic resonances are crucial probes to understand the various phases of matter created during relativistic heavy-ion collisions. Due to their short lifetimes, the yields of these resonances can be affected by competing rescattering and regeneration mechanisms in the final hadronic phase. Rescattering can alter the momentum of the resonance decay products, limiting their reconstruction...
Hypernuclei are bound states of hyperons (Y) and nucleons (N). Measurements on their yields can help us investigate their production mechanisms. In particular, the ${}^5_{\Lambda}$He and $^{4}_{\Lambda}$H(e) are bounded substantially tighter compared to the $^{3}_{\Lambda}$H. The large radius of the $^{3}_{\Lambda}$H leads to suppression in coalescence models, but not in the thermal model...
Strangeness production has been suggested as a sensitive probe to the early dynamics of the deconfined matter created in heavy-ion collisions.
There are significant discussions in the field about the initial conditions, including the colliding energy and the size of the system, needed to generate a quark-gluon plasma (QGP). It is expected that the threshold can be revealed by the measurements...
Hypernuclei are bound states of nucleons and hyperons. The measurement of the production of hypernuclei with mass number A=3 and 4 in heavy-ion collisions is a powerful tool to investigate the hyper-nucleosynthesis mechanism. In the coalescence model, the production yields are sensitive to the interplay between the spatial extension of the nucleus wavefunction and the baryon-emitting source...
Understanding the properties of hypernuclei is crucial for constraining the nature of hyperon-nucleon ($Y\text{-}N$) interactions, which plays a key role in determining the inner structure of compact stars. The lightest (anti-)hypernuclei are the hypertriton ($^3_\Lambda\text{H}$), which consists of a pair of nucleons and a $\Lambda$ hyperon, and its anti-nucleus...
