“…We fit m c , µ R , and µ F to the latest available data on charm production [7,8,9,10] in proton-nucleon and pion-nucleon collisions. We use mainly the data on pN collisions, which are more relevant to us, but examine also the πN data to see how well our choice of parameters works there.…”

“…The data we used for the 'calibration' of the MNR program are shown in Table 1 and Table 2 [7,8,9,10]. These tables also present a comparison of experimental data on total inclusive D-production cross sections (converted to σ cc total cross sections) with those calculated with the MNR program.…”

“…In the case of πN collisions ( Table 2) the factor 2 in equation (6) is replaced by 1.6, which is the value of σ cc /σ cc (x F > 0) when a pion beam is used. Table 1 [7], using the program with the four different PDFs.…”

“…Today, however, pQCD predictions and experimental data are known to be compatible [6,7,8,9,10]: charm production experiments form a consistent set of data, and the inclusion of next-to-leading order (NLO) terms has been a major improvement over the leading-order treatment. Quoting from Appel [6], "the success of these calculations has removed the impetus to look for unconventional sources of charm production beyond the basic QCD".…”

Prompt atmospheric neutrinos and muons: NLO versus LO QCD predictions

2000

We compare the leading and next-to-leading order QCD predictions for the flux of atmospheric muons and neutrinos from decays of charmed particles. We find that the full NLO lepton fluxes can be approximated to within ϳ10% by the Born-level fluxes multiplied by an overall factor of 2.2Ϫ2.4, which depends slightly on the PDF. This supports the approach of Thunman, Ingelman and Gondolo. We also find that their very low lepton fluxes are due to the mild slope they used for the gluon distribution function at small momentum fractions, and that substantially larger lepton fluxes result when the slope of the gluon distribution function at small momentum fractions is larger.

We measure the neutral D total forward cross section and the differential cross sections as functions of Feynman-x (x F ) and transverse momentum squared for 500 GeV/c π − -nucleon interactions. The results are obtained from 88 990±460 reconstructed neutral D mesons from Fermilab experiment E791 using the decay channels D 0 → K − π + and D 0 → K − π + π − π + (and charge conjugates). We extract fit parameters from the differential cross sections and provide the first direct measurement of the turnover point in the x F distribution, 0.0131±0.0038. We measure an absolute D 0 +D 0 (x F >0) cross section of 15.4 − + 2.3 1.8 µbarns/nucleon (assuming a linear A dependence). The differential and total forward cross sections are compared to theoretical predictions and to results of previous experiments.

Open charm contribution to dilepton spectra produced in nuclear collisions at SPS energies

Measurements of open charm hadro-production from CERN and Fermilab experiments are reviewed, with particular emphasis on the absolute cross sections and on their A and √ s dependences. Differential p T and x F cross sections calculated with the Pythia event generator are found to be in reasonable agreement with recent data. The calculations are scaled to nucleusnucleus collisions and the expected lepton pair yield is deduced. The charm contribution to the low mass dilepton continuum observed by the CERES experiment is found to be negligible. In particular, it is shown that the observed low mass dilepton excess in S-Au collisions cannot be explained by charm enhancement.
