Multiplicity of charged particles in Pb-Pb collisions at SPS energies
The NA57 collaboration
The multiplicity of charged particles in the central rapidity region has been measured by the NA57 experiment in Pb--Pb collisions at the CERN SPS at two beam momenta: 158 A GeV/{\…
Energy dependence of hyperon production in nucleus-nucleus collisions at SPS
The NA57 Collaboration
A measurement of strange baryon and antibaryon production in Pb-Pb collisions has been carried out by the NA57 experiment at the CERN SPS, with 40 and 158 A GeV/c beam momentum. Re…
A model of binary collisions dependence of jet quenching in nuclear collisions at ultrarelativistic energies
Roman Lietava, Jan Pisut, Neva Pisutova +1
We describe a model of jet quenching in nuclear collisions at RHIC energies. In the model, jet quenching is to be caused by the interruption of jet formation by nucleons arriving a…
An alternative model of jet suppression at RHIC energies
Roman Lietava, Jan Pisut, Neva Pisutova +1
We propose a simple Glauber-type mechanism for suppression of jet production up to transverse momenta of about 10 GeV/c at RHIC. For processes in this kinematic region, the formati…
On energy densities reached in heavy-ion collisions at the CERN SPS
Jan Pisut, Neva Pisutova, Boris Tomasik
We present a few estimates of energy densities reached in heavy-ion collisions at the CERN SPS. The estimates are based on data and models of proton-nucleus and nucleus-nucleus int…
An alternative way of plotting the data and results of models of J/psi suppression
Jan Pisut, Neva Pisutova
We propose an alternative way of looking at data on anomalous J/psi suppression. The proposed method is in principle equivalent to the one used by the NA50 Collaboration, but it pe…
The effect of gluon depletion on J/psi suppression in pA and AA collisions
Rudolph C. Hwa, Jan Pisut, Neva Pisutova
The enhanced suppression of production at large in collisions is studied in the framework of gluon depletion at large . The nonperturbative process that modif…
Nucleon number dependence of the onset of anomalous J/psi suppression and the dynamics of nuclear collisions
Anna Nogova, Neva Pisutova, Jan Pisut
We point out that data on the onset of anomalous J/psi suppression as a function of nucleon numbers A and B could provide information on the dynamics of nuclear interactions. In pa…
Phenomenological Evidence for Gluon Depletion in pA Collisions
R. C. Hwa, J. Pisut, N. Pisutova
The data of J/psi suppression at large x_F in pA collisions are used to infer the existence of gluon depletion as the projectile proton traverses the nucleus. The modification of t…
A model of anomalous production of strange baryons in nuclear collisions
Roman Lietava, Jan Pisut, Neva Pisutova +1
We propose a simple model of production of strange baryons and antibaryons in nuclear collisions at the CERN SPS. The model takes into account both the increase of strangeness prod…
Strangeness production in nuclear interactions at 200 AGeV and the number of nucleon-nucleon collisions
Roman Lietava, Jan Pisut
Data on mean numbers of , , K's and on the total number of pairs of strange valence quarks in final state hadrons in hadronic and nuclear collisions at CERN-…
Bose-Einstein Correlations from Random Walk Models
Boris Tomasik, Ulrich Heinz, Jan Pisut
We argue that strong final state rescattering among the secondary particles created in relativistic heavy ion collisions is essential to understand the measured Bose-Einstein corre…
Enhanced J/psi suppression due to gluon depletion
R. C. Hwa, J. Pisut, N. Pisutova
The nonlinear effect of gluon depletion in the collision of large nuclei can be large. It is due to multiple scatterings among comoving partons initiated by primary scattering of p…
Hadron Formation Time and Dilepton Mass Spectra in Heavy Ion Collisions
Peter Filip, Jan Pisut
We point out that formation time of pions produced in heavy ion collisions modifies the mass spectrum of dileptons produced via pipi -> ee annihilation. Increasing formation time e…
The Role of Gluon Depletion in J/psi Suppression
R. C. Hwa, J. Pisut, N. Pisutova
The depletion of gluons as the parton flux traverses a nucleus in a heavy-ion collision can influence the production rate of heavy-quark states. Thus the suppression of can b…
Nucleon number dependence of longitudinal radii in ion-ion collisions as a signature of the onset of collective expansion
Jan Pisut, Neva Pisutova, Petr Zavada
In an attempt to disentangle the effects of nuclear geometry from those of nuclear geometry we study dependence of longitudinal radius on nucleon numbers of colliding nuclei within…
Contribution of intermediate stage gluons to J/Psi suppression in Lead-Lead collisions at 158 AGeV
Jan Ftacnik, Jan Pisut, Neva Pisutova
We point out that dissociation of J/Psi by partons (mostly gluons) present in the intermediate stage of heavy-ion collisions can explain J/Psi suppression observed recently by the…
