Nucleation Rate of Hadron Bubbles in Baryon-Free Quark-Gluon Plasma

We evaluate the factor $\kappa$ appearing in Langer's expression for the nucleation rate extended to the case of hadron bubbles forming in zero baryon number cooled quark-gluon plasma. We consider both the absence and presence of viscosity and show that viscous effects introduce only small changes in the value of $\kappa$Comment: 9 pages, revtex, no figures Full postscript version available at via the WWW at http://nucth.physics.wisc.edu/preprints/ or by via from ftp://nucth.physics.wisc.edu/pub/preprints/mad-nt-95-06.p

Black Holes in Cascading Theories: Confinement/Deconfinement Transition and other Thermal Properties

We present numerical evidence for a transition between the Klebanov-Strassler background and a solution describing a black hole in the class of cascading solutions in the chirally restored phase. We also present a number of properties of this solution, including the running of the coupling constant, the viscosity to entropy ratio and the drag force on a quark moving in this background.Comment: 34 pages, 7 figures.

Domain Wall Dynamics of Phase Interfaces

The statics and dynamics of a surface separating two phases of a relativistic quantum field theory at or near the critical temperature typically make use of a free energy as a functional of an order parameter. This free energy functional also affords an economical description of states away from equilibrium. The similarities and differences between using a scalar field as the order parameter versus the energy density are examined, and a peculiarity is noted. We also point out several conceptual errors in the literature dealing with the dynamical prefactor in the nucleation rate.Comment: 12 pages plus 5 figure

Quantum Chaos at Finite Temperature

We use the quantum action to study quantum chaos at finite temperature. We present a numerical study of a classically chaotic 2-D Hamiltonian system - harmonic oscillators with anharmonic coupling. We construct the quantum action non-perturbatively and find temperature dependent quantum corrections in the action parameters. We compare Poincar\'{e} sections of the quantum action at finite temperature with those of the classical action.Comment: Text (LaTeX), Figs. (ps

Microscopic calculations of stopping and flow from 160AMeV to 160AGeV

The behavior of hadronic matter at high baryon densities is studied within Ultrarelativistic Quantum Molecular Dynamics (URQMD). Baryonic stopping is observed for Au+Au collisions from SIS up to SPS energies. The excitation function of flow shows strong sensitivities to the underlying equation of state (EOS), allowing for systematic studies of the EOS. Effects of a density dependent pole of the $\rho$-meson propagator on dilepton spectra are studied for different systems and centralities at CERN energies.Comment: Proceedings of the Quark Matter '96 Conference, Heidelberg, German

Prompt K_short production in pp collisions at sqrt(s)=0.9 TeV

The production of K_short mesons in pp collisions at a centre-of-mass energy of 0.9 TeV is studied with the LHCb detector at the Large Hadron Collider. The luminosity of the analysed sample is determined using a novel technique, involving measurements of the beam currents, sizes and positions, and is found to be 6.8 +/- 1.0 microbarn^-1. The differential prompt K_short production cross-section is measured as a function of the K_short transverse momentum and rapidity in the region 0 < pT < 1.6 GeV/c and 2.5 < y < 4.0. The data are found to be in reasonable agreement with previous measurements and generator expectations.Comment: 6+18 pages, 6 figures, updated author lis

Impact of right ventricular dysfunction and end-diastolic pulmonary artery pressure estimated from analysis of tricuspid regurgitant velocity spectrum in patients with preserved ejection fraction

AIMS: We aimed to analyse the association between right haemodynamic parameters, right ventricular (RV) dysfunction parameters, and outcomes in patients with preserved ejection fraction (EF). METHODS AND RESULTS: Retrospective analysis of right haemodynamic (systolic pulmonary pressure and end-diastolic pulmonary pressure based on tricuspid regurgitation (TR) velocity at pulmonary valve opening time), and RV parameters including size (end-diastolic and end-systolic area), function (RV fractional area change, Tei index, Tricuspid Annular Plane Systolic Excursion, and speckle tracking derived free wall strain), from 557 consecutive patients with preserved EF [EF >/= 50%; age 64.9 + 20; 52% female; co-morbidity Charlson index 4.7 (2.9, 6.4)]. All cause and cardiac mortality were retrospectively analysed and correlated to echo haemodynamic and co-morbid parameters. TR velocity at pulmonary valve opening time and calculated end-diastolic pulmonary artery pressure were obtainable in 71% of patients. The best haemodynamic univariate predictor of mortality was calculated end-diastolic pulmonary artery pressure [hazard ratio 1.06 (1.04-1.07); P < 0.0001], superior to TR peak velocity and systolic pulmonary artery pressure. Elevated end-diastolic pulmonary artery pressure was associated with all cause and cardiac mortality even when adjusted for all significant clinical (age, gender, and Charlson index), and echo (stroke volume index, left atrial volume index, systolic pulmonary pressure, E/e', and Tei index) parameters. Tei index was superior to all other RV functional parameters (P < 0.05 for all parameters). CONCLUSION: TR velocity at pulmonary valve opening time and calculated end-diastolic pulmonary artery pressure are obtainable in most patients, and add prognostic information on top of clinical and routine haemodynamic and diastolic parameters
