Abstract

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 $d^{2} σ d x_{F} d P^{2}_{T} = 12 [σ (D / D)(n+1)b](1−|x_{F} |)^{n} exp (−bp^{2}_{T}) with n=4.9 ± 0.5, b=(1.0±0.1)(GeV /c)^{−2}$ , 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.

Charmed hadron production in pp collision
2007, Astroparticle Physics
We investigated the production of charmed hadrons (D⁺, D⁻, D⁰, ${\bar{D}}^{0}$ , $Λ_{c}^{+}$ , ${\bar{Λ}}_{c}^{-}$ ) in pp collisions as a function of $\sqrt{s}$ , x_F, $p_{⊥}^{2}$ and p_⊥ in the framework of the QGSJET model. The study of charmed hadron production characteristics in pp collision is particularly important for cosmic ray physics in the context of atmospheric prompt lepton fluxes. Here our aim is to check the reliability of the QGSJET model to be used to study the production of charmed hadrons in cosmic ray hadronic interactions with air nuclei. Charmed hadroproduction cross sections or the charmed hadron average multiplicities in pp collisions are relatively very small. The maximum production of all charmed hadrons takes place with low values of x_F, $p_{⊥}^{2}$ , and p_⊥ within a small range for all values of $\sqrt{s}$ under study. Charmed hadroproduction cross sections as a function of x_F and $p_{⊥}^{2}$ are compared with the LEBC-EHS and LEBC-MPS experiment data for D-meson production. The agreement is quite satisfactory for smaller values of $p_{⊥}^{2}$ (⩽2 (GeV/c)²). There is an asymmetry in charmed hadroproduction in pp collision. For all x_F, asymmetry is prominent in the low value of $\sqrt{s}$ . There is a strong preference for producing $Λ_{c}^{+}$ rather than ${\bar{Λ}}_{c}^{-}$ -baryons, while that for producing $\bar{D}$ rather than D-mesons for this range of $\sqrt{s}$ . Asymmetry increases from zero to ±1 around x_F = 0.3 for all values of $\sqrt{s}$ and for all charmed hardron groups. The patterns of asymmetric production of different charmed hadrons with x_F are approximately the same as that with $\sqrt{s}$ . We compare our calculation with the data from Fermilab experiment E781 (SELEX) for Λ_c-baryon production. The agreement is quite good. The asymmetry of charmed hadroproduction with p_⊥ does not follow any well defined pattern.
Limits on the mixing of tau neutrino to heavy neutrinos
2002, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
Limits at 90% c.l. on the square of the mixing strength |U_τ4|² between ν_τ and a mostly isosinglet heavy neutrino with mass in the range 10–290 MeV/c² are reported. The results were derived using the negative result of a search for neutral particles decaying into two electrons conducted by the CHARM Collaboration in a neutrino beam dump experiment. Upper limits ≅10⁻⁴ were obtained for neutrino masses larger than 160 MeV/c².
Leading charm in hadron-nucleus interactions in the intrinsic charm model
1999, Nuclear Physics B
Leading charm hadrons produced in hadron-nucleus interactions cannot be adequately described within the parton fusion model. Recent results on charm baryon production in Σ⁻ A interactions at 330 GeV with the WA89 detector disagree with fusion predictions. Intrinsic heavy quark pairs in the Σ⁻ (dds) wavefunction provide a simple mechanism for producing fast charm hadrons. We calculate leading charm baryon production from Σ⁻, π⁻ and p projectiles in a two component model combining parton fusion with intrinsic charm. Final state D⁻, Σ_c⁰, Ξ_c⁺, and Λ_c⁺ dσ/dx_F distributions and $D^{−} /D^{+}, D_{s}^{−} /D_{s}^{+} and Λ_{c}^{+} / Λ_{c}^{+}$ asymmetries are compared to WA89 data. Predictions are made for 650 GeV Σ⁻ A and π⁻ A interactions in the SELEX detector at Fermilab and for 800 GeV pA interactions.
Prompt ν<inf>τ</inf> background in wide band ν<inf>μ</inf> beams
1997, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
To estimate the prompt background for ν_μ → ν_τ oscillation search in the Chorus and Nomad experiments, two possible sources of tau-neutrinos were considered. The first is the production and (semi-)leptonic decay of heavy flavour mesons. Secondly, the Drell-Yan mechanism can lead to tau-pairs. It is shown that this last contribution is negligible. However, the decay of D_s^± mesons to τ^±ν_τ gives rise to 3.3 × 10⁻⁶ ν_τ charged-current interactions per ν_μ charged-current interaction. Over the course of the Chorus experiment, this corresponds to 0.1 detected ν_τ charged-current events. This value is an upper limit and the actual background might be smaller by a factor of 2. However, it should carefully be taken into account, especially in view of future experiments, wishing to explore smaller values of mixing.
Charmed hadron asymmetries in the intrinsic charm coalescence model
1996, Nuclear Physics B
Fermilab experiment E791, measuring charmed hadron production in π⁻A interactions at 500 GeV with high statistics, has observed a strong asymmetry between the hadroproduction cross sections for leading D mesons which contain projectile valence quarks and the non-leading charmed mesons without projectile valence quarks. Such correlations of the charge of the D meson with the quantum numbers of the beam hadron explicitly contradict the factorization theorem in perturbative QCD which predicts that heavy quarks hadronize through a jet fragmentation function that is independent of the initial state. The E791 experiment also measures $Λ_{c} / Λ_{c}$ and $D_{s} / D_{s}$ production asymmetries as well as asymmetries in $D D$ pair production. We examine these asymmetries and the fractional longitudinal momentum, x_F, distributions for single and pairs of charmed hadrons within a two-component model combining leading-twist gg and $q q$ fusion sub-processes with charm production from intrinsic heavy quark Fock states. A key feature of this analysis is intrinsic charm coalescence, the process by which a charmed quark in the projectile's Fock state wave function forms charmed hadrons by combining with valence quarks of similar rapidities.
Charm production and high energy atmospheric muon and neutrino fluxes
1996, Astroparticle Physics
Production of muons and neutrinos in cosmic ray interactions with the atmosphere has been investigated with Monte Carlo models for hadronic interactions. The resulting conventional muon and neutrino fluxes (from π and K decays) agree well with earlier calculations, whereas our prompt fluxes from charm decays are significantly lower than earlier estimates. Charm production is mainly considered as a well defined perturbative QCD process, but we also investigate a hypothetical non-perturbative intrinsic charm component in the proton. The lower charm rate implies better prospects for detecting very high energy neutrinos from cosmic sources.
