A database is under construction to provide a complete collection of published basic properties of hypernuclei such as {\Lambda} binding energies, lifetimes, or excitation energies. From these values, averages with related errors are computed in a systematic way. For each property, the overall experimental situation is depicted in form of an ideogram showing the combined probability density function of the measurements. The database is accessible via a dynamic website at https://hypernuclei.kph.uni-mainz.de with an user interface offering customizable visualizations, selections, or unit conversions. The capabilities of the database are demonstrated for the puzzling and disputed data situation of the hypertriton.

  1. Questioning MAMI's recent determination of $B_{\Lambda}({_{\Lambda}^3}{\rm H})$

    nucl-th 2026-04 unverdicted novelty 6.0

    The observed pion momentum line at 113.8 MeV/c is reinterpreted as coming from ground-state Lambda-7He decay to the 478 keV excited state of Li-7 rather than from Lambda-3H decay.

  2. Collision Energy Dependence of Hypertriton Production in Au+Au Collisions at RHIC

    nucl-ex 2026-04 unverdicted novelty 6.0

    Hypertriton yields and Lambda ratios increase at lower collision energies but remain a factor of two below thermal models, while the double ratio to triton production stays constant at 0.4, pointing to intrinsically l...
