We present the first measurement of pseudorapidity densities primary charged particles near midrapidity in Au+Au collisions at sqrt[s(NN)] = 56 and 130 GeV. For most central collisions, we find charged-particle density to be dN/deta|(|eta|<1) 408+/-12(stat)+/-30(syst) GeV 555+/-12(stat)+/-35(syst) GeV, values that are higher than any previously observed nuclear collisions. Compared proton-antiproton our data show an increase per participant by more 40% energy.
Interactions of 200-GeV/c protons and antiprotons on hydrogen, argon, xenon targets were studied with a streamer-chamber vertex spectrometer at the CERN SPS. Results multiplicities, rapidity distributions, correlations are presented compared predictions current models.
In this note, using the simplified colour string model, we study configuration space distribution of stopped nucleons in heavy-ion collisions.Given find that from target and projectile end up separated each other by a distance which increases with collision energy.In consequence, for center-of-mass energies larger than 6 or 10 GeV (depending on details model), it appears are not necessarily thermal chemical equilibrium, net-baryon density reached is likely much higher already present...
As the beam energy increases colliding nuclei are expected to become more transparent each other, with not only fewer baryons in central rapidity region, but even possibly separated configuration space. This is an important property which authors propose study via Hanbury-Brown--Twiss intensity interferometry of stopped protons. Their calculations suggest that such measurements may help obtain information on equation state nuclear matter relevant a wide range phenomena including neutron...
We propose a generalization of the Bjorken in-out Ansatz for fluid trajectories, which, when applied to 1+1 hydrodynamic equations, generates one-parameter family analytic solutions interpolating between boost-invariant picture and non-boost-invariant one by Landau. This parameter characterizes proper-time scale velocities approach Ansatz. discuss resulting rapidity distribution entropy various freeze-out conditions compare it with original Landau results.
Boost-invariant solutions of Boltzmann-Vlasov equations for quark-antiquark plasma are studied. A simple example is presented showing an apparently general feature the plasma: oscillations quarks and antiquarks in mean chromoelectric field. The energy loss by electromagnetic radiation estimated.
Particle production in $\mathrm{Au}\text{\ensuremath{-}}\mathrm{Au}$, $\mathrm{Cu}\text{\ensuremath{-}}\mathrm{Cu}$, $d$-Au, and $p\text{\ensuremath{-}}p$ collisions at 200 GeV c.m. energy are analyzed the wounded quark-diquark model. Existing data well reproduced. Emission functions of unwounded constituents determined. Implications for collective evolution system discussed.
Transverse-momentum distribution of quark-antiquark pairs created---through tunneling---from chromoelectric flux tubes an arbitrary field strength spanned between two color charges is computed and its properties discussed. It also argued that such nonelementary may be responsible for large-${p}_{\ensuremath{\perp}}$ tails recently observed in nucleus-nucleus collisions at energies \ensuremath{\gtrsim}100 GeV per nucleon, shorter qq\ifmmode\bar\else\textasciimacron\fi{} formation times...
History and recent developments of the concept wounded hadronic constituents are summarized, with special attention to quark–diquark model particle production in nucleon–nucleon nucleus–nucleus collisions.
