Systematic treatment of hypernuclear data and application to the hypertriton

TL;DR

This paper introduces a comprehensive hypernuclear database that systematically compiles and visualizes experimental data, demonstrated through the analysis of the hypertriton's properties.

Contribution

It presents a new, systematically curated hypernuclear database with dynamic visualization tools, addressing the complex data situation of the hypertriton.

Findings

Database provides complete hypernuclear property data.

Visualizations reveal data inconsistencies and uncertainties.

Application to hypertriton highlights data disputes.

Abstract

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.
