“…In Table 2 we also present a similar analysis for πN collisions, using only MRS R1 for simplicity. In this case slightly higher values of m c fit the πN data [7, 10] a bit better, while m c = 1.185 GeV, the value we take with the MRS R1 PDF, fits the pN data [7,8,10] a bit better. Notice that for the pions we used a different PDF, SMR2 [21], the same used in Refs.…”

“…is the transverse mass. The current procedure to reproduce the measured differential cross sections [8,9,10] is to use the MNR default choices for these three parameters and multiply the result by the global factor of about 2 or 3 necessary to match the predicted and measured total inclusive cross sections. Although this procedure might be acceptable in face of the uncertainties in the pQCD predictions, we find it unsatisfactory from a theoretical point of view.…”

“…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.…”

“…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

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.

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.

DsTau: study of tau neutrino production with 400 GeV protons from the CERN-SPS

In the DsTau experiment at the CERN SPS, an independent and direct way to measure tau neutrino production following high energy proton interactions was proposed. As the main source of tau neutrinos is a decay of D s mesons, produced in proton-nucleus interactions, the project aims at measuring a differential cross section of this reaction. The experimental method is based on a use of high resolution emulsion detectors for effective registration of events with short lived particle decays. Here we present the motivation of the study, details of the experimental technique, and the first results of the analysis of the data collected during test runs, which prove feasibility of the full scale study of the process in future.
