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 article, the authors measured the inclusive cross sections for forward D meson production at s =26 GeV in π − p interactions and showed that the p T 2 distribution is exponential with slope parameter [−1.18 −0.16 +0.18 ]( GeV / c) −2.

TL;DR: In this paper, the authors measured the inclusive production properties of D and D messons produced from pp interactions at s =27.4 GeV, and the differential production cross section is well represented by the empirical form d 2 σ d x F d P 2 T = 1 2 [σ ( D / D )(n+1)b](1−|x F |) n exp (−bp 2 T ) with n=4.9 ± 0.5, b=(1.0± 0.3) ωb.

TL;DR: In this paper, a study of the properties of charm particles produced in 360 GeV/c π-p interactions is reported, which is performed using the high resolution hydrogen bubble chamber LEBC in association with the European Hybrid Spectrometer at the CERN SPS.

TL;DR: Based on a sample of 22 four-prong D 0 / D 0 decays produced in hydrogen by 360 GeV/ c π −, this paper presented the following new results: mean lifetime τ = (3.5 −0.4 ) x 10 −13 s; production cross section for x F > 0.0, σ = (10.3 ± 3.5) ωb ; the D → K ± π ± ρ + π− branching ratio = (7.1 ± 2.9 + 1.5).
