Parallel Session T16: Light nuclei production
- Yuriy Sinyukov (Bogolyubov Institute for Theoretical Physics)
In the scope of the FAIR Phase-0 physics program, the HADES collaboration recorded 13.7 billion Ag(1.58A GeV)+Ag events in March 2019. With an available energy of 2.55 GeV in binary nucleon nucleon collisions, the lightest hadrons containing strangeness are produced at their free nucleon nucleon threshold energy. Therefore, they are ideal probes to investigate medium effects due to their steep...
The study of hypernuclei and their production mechanisms open new opportunities for nuclear/particle physics and astrophysics. The hyperons influence many nuclear properties in finite nuclei and in neutron stars (infinite nuclear matter). We review the main processes leading to the production of hypernuclei in nuclear reactions including relativistic ion collisions. Such deep-inelastic...
Space: the final frontier for antinuclei physics. There, antinucleosynthesis models already tested on the bench of hadronic colliders and particle physics experiments are put at work to crack one of the biggest problems of modern physics: the existence and nature of dark matter.
In fact, the observation of an antinucleus in cosmic rays would most probably mean a breakthrough in searches for...
Light nuclei production is predicted to be sensitive to local baryon density fluctuations and can be used to probe the QCD phase structure and the properties of medium created in heavy-ion collisions. Since 2018, the STAR experiment has collected high statistics data in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}$ = 3 GeV (BES-II fixed-target mode), 14.6, 19.6 GeV (BES-II collider mode) and...
The ${{}^{3}_{\Lambda}\mathrm{H}}$ is a bound state of proton (p), neutron (n) and Λ. Studying its characteristics provides insights about the strong interaction between the lambda and ordinary nucleons. In particular, the ${{}^{3}_{\Lambda}\mathrm{H}}$ is an extremely loosely bound object, with a large wave-function. As a consequence, the measured (anti) ${{}^{3}_{\Lambda}\mathrm{H}}$...
Light nuclei and hypernuclei are expected to be abundantly produced in intermediate to low energy heavy-ion collisions due to the high baryon density. However, their production mechanisms are currently not well understood. Measurements of the yield and collective flow are sensitive to their production mechanisms and the dynamics of the produced medium. In particular, hypernuclei measurements...
The formation of light (anti)nuclei in heavy-ion collisions as well as in hadron collisions has been studied experimentally and theoretically for many decades. Two competing (anti)nucleosynthesis models are typically used to describe light (anti)nuclei yields and their ratios to other hadrons in heavy-ion collisions: the statistical hadronization model (SHM) and the nucleon coalescence...
