Observation of J/ψ production by neutrinos in the calorimeter of the CHORUS detector exposed to the CERN SPS wide-band νμ beam is reported. A spectrum-averaged cross section σJ/ψ = (6.3 ± 3.0) × 10-41 cm2 is obtained for 20 GeV ≤ Eν ≤ 200 GeV. The data are compared with the theoretical model based on the QCD Z-gluon fusion mechanism.

Abstract
Observation of J/ψ production by neutrinos in the calorimeter of the CHORUS detector exposed to the CERN SPS wide-band νμ beam is reported. A spectrum-averaged cross section σJ/ψ = (6.3 ± 3.0) × 10-41 cm2 is obtained for 20 GeV ≤ Eν ≤ 200 GeV. The data are compared with the theoretical model based on the QCD Z-gluon fusion mechanism.File in questo prodotto:
