Diffractive dissociation reaction np → Λ0K0p for incident neutron momenta between 30 and 70 GeV/c

We present results of the exclusive diffractive reaction np → Λ0K0p at 0·08 < |t|< 0·53 GeV2/c2 and momenta between 30–70 GeV/c at the Serpukhov neutron beam. Thet-dependence is exp (Bt) withB= 11·4± 2·3 (GeV/c)−2 and it exhibits the diffractive minimum at ¦t¦ 0·28 GeV2/c2 for Λ0K0 massesM < 1·8 GeV/c2.B decreases with increasingM. Correlation with the beam direction is observed in the rest frame of the Λ0K0 system: the cross section rises for the forward-going Λ0. The rise is more pronounced for higherM. The cross section of reaction np → Λ0K0p for 0<|t|< 0·53 GeV2/c2 is 10·3 ± 2·5 ± 2·8 μb.
