Feasibility study for measurement of beta-decay rates of Λ hypernuclei

The baryon structure may be modified in nuclear medium. The quark meson coupling model predicts that the beta decay rate of a Λ hyperon in Λ hypernuclei decreases by 20% at maximum. We propose an experiment to precisely measure the beta-decay rate of 5ΛHe at J-PARC via the (π+, K+) reaction. A feasi...
