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: The European hybrid spectrometer (EHS) was used in the NA27 experiment to study charm particles produced in 360 GeV c π-p and 400 GeVc pp interactions.

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, the authors measured the 12D0 and 10D± exclusive branching ratio with the analysis of 608 spatially resolved charm particle decays produced in 360 GeV/c π−p and 400 geV/cpp interactions.
