$D$ Meson Production From 400 GeV/$c p p$ Interactions

The LEBC-EHS collaboration Aguilar-Benitez, M. ; Allison, W.W.M. ; Bailly, J.L. ; et al.

Phys.Lett.B 189 (1987) 476, 1987.

Inspire Record 245101 DOI 10.17182/hepdata.12913

We have measured the inclusive production properties of D and D messons produced from pp interactions at s =27.4 GeV . 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±0.1)( GeV /c) −2 , and the inclusive D / D cross section σ ( D / D ) is (30.2±3.3) ωb. The QCD fusion model predicts D / D production which is in good agreement with our data except for the magnitude of the cross section which depends sensitively on the assumed mass of the charm quark.

A Study of pi- p --> f0 n Reaction at Momenta Up to 50-GeV/c

Bolotov, V.N. ; Isakov, V.V. ; Kakauridze, D.B. ; et al.

Phys.Lett.B 52 (1974) 489, 1974.

Inspire Record 90366 DOI 10.17182/hepdata.19110

A mass spectrum of π o π o system in the final state of π − p → π o π o n reaction has been studied at the momenta 20 to 50 GeV/ c . The experiments were performed at the 70 GeV IHEP accelerator. In the mass distribution there has been selected a peak corresponding to f o meson production cross section decreases in the power form with the momentum. The differential cross section follows exponential dependence, exp ( bt ).

A Study on pi- Charge Exchange Reactions on Nuclei at 48-GeV/c

Bolotov, V.N. ; Isakov, V.V. ; Kakauridze, D.B. ; et al.

Nucl.Phys.B 85 (1975) 158-164, 1975.

Inspire Record 90365 DOI 10.17182/hepdata.32132

The charge-exchange cross sections were measured for π − on Li, C, Al and Cu nuclei at momentum 48 GeV/ c . By comparing the data obtained for nuclei with those for hydrogen under the same conditions the effective numbers of protons are defined. The conclusion is made that η 0 mesons are absorbed in nuclei weaker then π 0 . The total cross section of η 0 interactions with the nucleon is determined to be σ tot ( η 0 N) = 15 ± 5 mb in agre ement with the quark model.
