“…Such measurements also serve as an important baseline for charm production in proton-nucleus or deuteronnucleus (p + A or d + A), and nucleus-nucleus (A + B) collisions [22,23,24,25]. In the absence of any nuclear effects, charm production (since it is a point-like process) is expected to scale with the number of binary nucleonnucleon collisions (N coll ), which depends on the impact parameter of the nuclear collision and can be obtained from a Glauber calculation [26].…”

Muon production at forward rapidity (1.5 ≤ |η| ≤ 1.8) has been measured by the PHENIX experiment over the transverse momentum range 1 ≤ pT ≤ 3 GeV/c in √ s = 200 GeV p+p collisions at the Relativistic Heavy Ion Collider. After statistically subtracting contributions from light hadron decays an excess remains which is attributed to the semileptonic decays of hadrons carrying heavy flavor, i.e. charm quarks or, at high pT , bottom quarks. The resulting muon spectrum from heavy flavor decays is compared to PYTHIA and a next-to-leading order perturbative QCD calculation. PYTHIA is used to determine the charm quark spectrum that would produce the observed muon excess. The corresponding differential cross section for charm quark production at forward rapidity is determined to be dσcc/dy|y=1.6 = 0.243 ± 0.013(stat.) ± 0.105(data syst.) +0.049 −0.087 (PYTHIA syst.) mb.

“…It will be interesting to see whether charm production follows a similar pattern. Finally, open charm production at forward rapidity needs to be understood to fully interpret PHENIX J/ψ measurements at forward rapidity [24,25,51,52,53].…”

“…The experimental challenge is illustrated in Figure 6 where the notation "rare probes" is quantified in terms of the product of multiplicity times branching ratio. The points are calculated for central Au+Au collisions at 25 A GeV using either the HSD transport code [16] or the thermal model based on the corresponding temperature and baryon-chemical potential [17]. Mesons containing charm quarks are about 9 orders of magnitude less abundant than pions (except for the ψ' meson which is even more suppressed).…”

“…The dilepton decay of vector mesons is suppressed by the square of the electromagnetic coupling constant (1/137) 2 , resulting in a dilepton yield which is 6 orders of magnitude below the pion yield, similar to the multiplicity of multi-strange anti-hyperons. The CBM experiment will enter a new era of nuclear matter research by measuring rare diagnostic probes never observed before at FAIR energies, and thus has a unique [16] and the statistical model [17]. For the vector mesons (ρ, ω, φ, J/ψ, ψ ) the decay into lepton pairs was assumed, for D mesons the hadronic decay into kaons and pions.…”

Abstract:The Compressed Baryonic Matter (CBM) experiment will be one of the major scientific pillars of the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt. The goal of the CBM research program is to explore the QCD phase diagram in the region of high baryon densities using high-energy nucleus-nucleus collisions. This includes the study of the equation-of-state of nuclear matter at high densities, and the search for the deconfinement and chiral phase transitions. The CBM detector is designed to measure both bulk observables with large acceptance and rare diagnostic probes such as charmed particles and vector mesons decaying into lepton pairs. PACS (

“…In fact, η meson production in heavy-ion collisions has been studied extensively both theoretically and experimentally, especially by the TAPS and HADES Collaborations, see, e.g., refs. [66][67][68][69][70][71][72][73][74][75]. Moreover, as pointed out earlier [66,67], because of the hidden strangeness (the ss component), η mesons experience weaker final state interactions compared to pions.…”

Effects of nuclear symmetry energy on η meson production and its rare decay to the dark U-boson in heavy-ion reactions

Using a relativistic transport model ART1.0, we explore effects of nuclear symmetry energy on η meson production and its rare decay to the dark U-boson in heavy-ion reactions from 0.2 to 10 GeV/nucleon available at several current and future facilities. The yield of η mesons at sub-threshold energies is found to be very sensitive to the density dependence of nuclear symmetry energy. Above a beam energy of about 5 GeV/nucleon in Au+Au reactions, the sensitivity to symmetry energy disappears. Using the branching ratio of the rare η decay (η → γU ) available in the literature, we estimate the maximum cross section for the U-boson production in the energy range considered, providing a useful reference for future U-boson search using heavy-ion reactions.PACS numbers: 21.65.Mn, 21.65.Ef, 95.35.+d
