Abstract

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

Abstract

In this paper we study the inclusive production of the charmed baryon Λ c + in interactions of 40–70 GeV/c neutrons with protons of hydrogen target. The experiment has been performed with the use of magnetic spectrometer BIS-2 located in the neutron beam of Serpukhov accelerator. The signal of Λ c + is observed in the effective mass spectra of Λ°π+π+π−. After the removal of interactions occurring on the container of liquid hydrogen, the signal consists of 14 combinations corresponding to ≈4 standard deviations of background. Its mean value is 2262 MeV/c2, width of the bin containing signal is 20 MeV/c2. On the basis of this signal we determine the value of cross section of Λ c + production times the branching ratio of its observed decay modeσ. Br (Λ c + → Λ°π+π+π−)=0·26±0·11 μb in the kinematic region ofx F>0·5 andp T
