Understanding the shortened lifetime of \boldmath$\text{isotope}[3][\Lambda ]H$\unboldmath

Abstract

The lifetime of the hypertriton $\text{isotope}[3][\Lambda ]H$ has been recently measured as significantly shorter than that of the free $\Lambda$. We present an explanation based on a change of the intrinsic hyperon decay due to the nuclear environment.
