The Weak Decay Widths of ?? Hypernuclei

Experimental Studies on the Weak Decay of Λ-Hypernuclei

“…[5]. Moreover, the comparison of the numbers quoted in row 5-7 of fourth column of Table II with the already mentioned experimental measurements [37], reported in the last column of the same Table, indicates a quite good agreement.…”

“…The obtained results are displayed as a function of the mass number A in Fig. 2, where the FINUDA values are compared with three previous sets of Γ p /Γ Λ determinations [33,35,37] and the theoretical predictions given in Ref. [5].…”

“…[3] [32]). Previous experimental results (brown circle [33], green diamonds [35] and, respectively, orange triangle [37]) are plotted for comparison. The solid magenta line represents the outcome of the calculations described in Ref.…”

“…5 Λ He and 11 Λ B hypernuclei The 12 Λ C hypernucleus is the unique system for which a complete experimental knowledge of its full pattern of weak decay widths is achieved [37]. This is a natural consequence of the fact that it is the most studied strange nuclear bound system.…”

“…Indeed, two proposals about the NMWD investigation were presented and approved to run at the J-PARC Hadron Experimental Facility (HEF). The first one, E18 [44], aims to increase by one order of magnitude the number of events previously collected by the SKS Collaboration on all the 12 Λ C NMWD channels [37]. The goal of the second proposal, E22 [45], is instead the exclusive study of the NMWD in A = 4 Λ-hypernuclei in order to verify the validity of the ∆I = 1/2 rule.…”
