Abstract:
|
The weak production of
Λ
’s in nucleon-nucleon scattering is studied in a meson-exchange framework. The weak transition operator for the
N

Λ
reaction is identical to a previously developed weak strangeness-changing transition potential
Λ

N
NN
that describes the nonmesonic decay of hypernuclei. The initial
NN
and final
YN
state interaction has been included by using realistic baryon-baryon forces that describe the available elastic scattering data. The total and differential cross sections as well as the parity-violating asymmetry are studied for the reaction

.
These observables are found to be sensitive to the opening of the
Σ
production channel, the choice of the strong interaction potential, and the structure of the weak transition potential. |
