Neutron and proton spectra from the decay of Lambda hypernuclei

# metadata.dc.description.abstract[].value
We have determined the spectra of neutrons and protons following the decay of 
Λ
 hypernuclei through the one- and two-nucleon-induced mechanisms. The momentum distributions of the primary nucleons are calculated and a Monte Carlo simulation is used to account for final state interactions. The shape of the proton spectrum is sensitive to the value of 
Γ
n
/
Γ
p
 the ratio of neutron- to proton-induced decay, and the available experimental information favors larger values than those predicted by the one-pion-exchange model. From the spectra we calculate the number of neutrons 
(
N
n
)
 and protons 
(
N
p
)
 per 
Λ
decay and show how the measurement of these quantities, particularly 
N
p
,
 can lead to a determination of 
Γ
n
/
Γ
p
.
 We also show that the consideration of the two-nucleon-induced channel has a repercussion on the results, widening the band of allowed values of 
Γ
n
/
Γ
p
 with respect to what is obtained neglecting this channel.
