As the lightest hypernucleus, hypertriton serves as an important benchmark for hypernuclear physics: its ground state spin, iso-spin and uniquely small binding energy (~130 keV) has been used to derive the fundamental property of YN interaction since its discovery. For a long time, it has been generally accepted that the hypertriton has a similar lifetime as free Lambda hyperon
because of the...
The hyperon-nucleon (Y-N) interaction is an essential ingredient in the description of the equation-of-state of high-baryon-density matter. Light hypernuclei (A = 3, 4), being simple Y-N bound states, serve as cornerstones of our understanding of the Y-N interaction. Precise measurements of the lifetimes of light hypernuclei can help provide input to our understanding in the Y-N...
In the last decade, ALICE has been one of the main experiments for the study of the (anti)(hyper) nucleosynthesis at collider.
From the study of the production of antinuclei in all collision systems to the measurement of the antinuclei interaction cross section with matter, ALICE is exploring the full spectrum of measurements involving (anti)(hyper)nuclei thanks to the copious amount of data...
Recent relativistic heavy ion (RHI) collision experiments have extracted conflicting values of the hypertriton (${}_\Lambda^3\mathrm{H}$) lifetime ($\tau({}_\Lambda^3\mathrm{H})$). While the ALICE Collaboration's reported $\tau({}_\Lambda^3\mathrm{H})$ is comparable to the free $\Lambda$ lifetime, the STAR Collaboration's reported value is considerably shorter. A similarly large spread of...
Direct $\Lambda n$ scattering data is extremely important and needed based on the newly confirmed Charge-Symmetry-Breaking (CSB) at a level of ~270 keV from the binding energy difference observed between ground states of $^4_{\Lambda}$He and $^4_{\Lambda}$H. Especially, the $\Lambda n$ data does not exist at all, thus the properties of $\Lambda n$ interaction has been assumed to be identical...
