TL;DR: In this article, a study of the properties of charm particles produced in 400 GeV/cpp interactions was performed using the high resolution hydrogen bubble chamber LEBC in association with the European Hybrid Spectrometer at the CERN SPS.

TL;DR: In this paper, the authors present the measurements of the Λc production cross section in proton-proton interactions at s = 27.4 GeV and give new limits on the exclusive branching ratio Λ c→pK+π−.

TL;DR: In this article, the differential distributions of D mesons produced in 400 GeV/c p-p interactions to the form d 2 σ d x F d p T 2 ∝(1−x F ) n exp [−(p T 2 /〈p T2 〉)] are discussed, and it is suggested that these distributions could reflect contribution of leading di-quarks in pp collisions.

TL;DR: In this article, the final results on the D-meson lift time measurements obtained by the NA27 experiment were presented, from a sample of 145 D 0 D 0 and 149 D ± decays, they have measured τ (D 0 )=(4.6 +0.6 −0.5 )×10 −13 s.

TL;DR: In this paper, a comparative analysis of the global properties of 400 GeV/c proton-proton interactions with and without charm production is presented, where multiplicities, momentum distributions, sphericity and thrust of these interactions are compared.
