“…[35] from data reported in ref. [30]. For our range of renormalization and factorization scales, the pp cross section with a 400 GeV beam energy is σ cc = 13.3 − 19.1 µb, with the lower cross section within 3σ and a central value of 16.2 µb that is about 12% lower than the central value of the measured pp charm pair cross section at this energy.…”

“…Our assumptions about hadronization and the incorporation of intrinsic transverse momentum are included in sec. 2, where we compare our NLO perturbative QCD transverse momentum distribution of D + + D − + D 0 +D 0 in pp collisions with E p = 400 GeV to LEBC-EHS measurements [30]. We show energy and rapidity distributions of charm hadrons to illustrate some of the features of charm production that translate through charm hadron decays to the neutrino energy and pseudorapidity distributions, at least approximately.…”

We present a new evaluation of the far-forward neutrino plus antineutrino flux and number of events from charm hadron decays in a 400 GeV proton beam dump experiment like the Search for Hidden Particles (SHiP). Using next-to-leading order perturbative QCD and a model for intrinsic charm, we include intrinsic transverse momentum effects and other kinematic angular corrections. We compare this flux to a far-forward flux evaluated with next-to-leading order perturbative QCD, without intrinsic transverse momentum, that used the angular distribution of charm quarks rather than the neutrinos from their decays. The tau neutrino plus antineutrino number of events in the perturbative QCD evaluation is reduced by a factor of about three when intrinsic transverse momentum and the full decay kinematics are included. We show that intrinsic charm contributions can significantly enhance the number of events from neutrinos from charm hadron decays. Measurements of the number of events from tau neutrino plus antineutrino interactions and of the muon charge asymmetry as a function of energy can be used to constrain intrinsic charm models.

In this work, charm production in the dpmjet hadronic jet simulation is compared to experimental data. Since the major application of dpmjet is the simulation of cosmic ray-induced air showers, the version of the code integrated in the CORSIKA simulation package has been used for the comparison. Wherever necessary, adjustments have been made to improve agreement between simulation and data. With the availability of new muon/neutrino detectors that combine a large fiducial volume with large amounts of shielding, investigation of prompt muons and neutrinos from cosmic ray interactions will be feasible for the first time. Furthermore, above 100 TeV charmed particle decay becomes the dominant background for diffuse extraterrestrial neutrino flux searches. A reliable method to simulate charm production in high-energy proton-nucleon interactions is therefore required.
