Lambda hyperonic effect on the normal driplines

TL;DR

This paper uses a generalized mass formula to study how adding Lambda hyperons affects the neutron and proton driplines, revealing the potential existence of bound hypernuclei beyond normal nuclear limits.

Contribution

It introduces a unified approach to compare normal and hypernuclei, showing that hyperons can extend nuclear stability boundaries.

Findings

Existence of bound hypernuclei with unbound normal cores

Lambda hyperons shift neutron and proton driplines

Hyperons can stabilize nuclei beyond conventional limits

Abstract

A generalized mass formula is used to calculate the neutron and proton drip lines of normal and lambda hypernuclei treating non-strange and strange nuclei on the same footing. Calculations suggest existence of several bound hypernuclei whose normal cores are unbound. Addition of Lambda or, Lambda-Lambda hyperon(s) to a normal nucleus is found to cause shifts of the neutron and proton driplines from their conventional limits.
