Title: Signals of spinodal hadronization: Strangeness trapping

Abstract

If the deconfinement phase transformation of strongly interacting matter is of first order and the expanding chromodynamic matter created in a high-energy nuclear collision enters the corresponding region of phase coexistence, a spinodal phase separation might occur. The matter would then condense into a number of separate blobs, each having a particular net strangeness that would remain approximately conserved during the further evolution. We investigate the effect that such strangeness trapping may have on strangeness-related hadronic observables. The kaon multiplicity fluctuations are significantly enhanced and thus provide a possible tool for probing the nature of the phase transition experimentally.

  • In an isentropic expansion of a baryon-rich quark-gluon plasma (QGP) formed in heavy-ion collisions and undergoing a first-order phase transition into a hadron-resonance gas, it is found that an analysis of the production cross sections of dimuons in the region where the invariant mass M is greater than 2.25 GeV is enough for the detection of a QGP, whereas an analysis in the region with Mapprox. >7.5 GeV is required for photon pairs. While the production cross section of dimuons is found to be almost independent of the equation of state used for the QGP, that for photon pairs dependsmore » on the equation of state of the QGP. We conclude that for the detection of the QGP muon pairs are better signals than photon pairs, whereas for a study of the equation of state of the QGP photon pairs seem to be more suitable than muon pairs.« less
  • In this paper, we investigate the gamma ray signal produced from dark matter collisions with high energy cosmic protons. Notably, we extend past results by including important hadronization effects. Showering and hadronization produces a high multiplicity of photons from the decays of hadrons, whose rate is not suppressed by the fine structure constant. Notably, proton remnants that do not participate in hard scattering, can produce a large rate of photons in the forward direction. These effects significantly enhance the photon rate and alter the energy and angular distributions compared to previous results which used only parton level calculations. Due tomore » this modification, the gamma ray signal from the nearby active galactic nuclei Centaurus A is potentially testable in future Fermi-LAT and HESS measurements, for a dark matter mass and coupling consistent with current XENON100 bounds.« less
  • The implications of the empirical signatures for the positivity of the strangeness magnetic moment {mu}{sub s} and the negativity of the strangeness contribution to the proton spin {delta}{sub s} on the possible uudss configurations of five quarks in the proton are analyzed. The empirical signs for the values for these two observables can only be obtained in configurations where the uuds subsystem is orbitally excited and the s antiquark is in the ground state. The configurations in which the s is orbitally excited, including the conventional K{sup +}{lambda}{sup 0} configuration, with the exception of that in which the uuds componentmore » has spin 2, yield negative values for {mu}{sub s}. Here, the strangeness spin {delta}{sub s}, strangeness magnetic moment {mu}{sub s}, and axial coupling constant G{sub A}{sup s} are calculated for all possible configurations of the uudss component of the proton. In the configuration with [4]{sub FS}[22]{sub F}[22]{sub S} flavor-spin symmetry, which is likely to have the lowest energy, {mu}{sub s} is positive and {delta}{sub s}{approx_equal}G{sub A}{sup s}{approx_equal}-1/3{mu}{sub s}.« less
  • We have found a simple powerful Ansatz, interpreting the Lund symmetric-fragmentation function as a universal production density, which predicts multiplicities and momentum and P/sub T//sup 2/ distributions of the many meson and baryon flavors observed in e/sup +/e/sup -/ collisions at E/sub c.m./approx. =30 GeV almost perfectly with only two ''natural'' parameters of the Lund symmetric-fragmentation function. The model depends only on hadron masses and not on quark-level suppression factors such as s/u or qq/q. At a minimum, it provides an easy basis for the prediction of particle production rates and distributions, and may provide insight into the actual productionmore » mechanism.« less
