In this research, pionic energy spectra of hypertriton H Λ 3 and H Λ 4 weak decay process are investigated in the frame work of Plane Wave Impulse Approximation (PWIA). The pionic energy spectra from H Λ 3 and H Λ 4 weak decay process are obtained by using Green's function method. Interaction between deuteron d-Λ is constructed by fitting the parameters of Isle type potential with a central repulsion and a single Gaussian potential with no repulsion (SG) which H reproduce the binding energy of hypertriton H Λ 3 . We have analyzed in detail the antisymmetrization of H Λ 3 which is the H origin of enhancement in H Λ 3 decay rate. This might solve the discrepancy issue of H Λ 3 decay life time between theoretical and experimental results. Similar analysis for H Λ 4 hypernucleus was conducted. [ABSTRACT FROM AUTHOR] |
