We propose to study the impact parameter dependence of the {bar {Lambda}}/{bar p} ratio in Pb(160A GeV)+Pb reactions. The {bar {Lambda}}/{bar p} ratio is a sensible tool to distinguish between hadronic cascade models and hydrodynamical models, which assume chemical equilibrium and incorporate a possible phase transition to a quark-gluon plasma. {copyright} {ital 1999} {ital The American Physical Society}

Enhanced antiproton production in Pb(160 A GeV)+Pb reactions: evidence for quark gluon matter?
Abstract The centrality dependence of the antiproton per participant ratio is studied in Pb(160 A GeV)+Pb reactions. Antiproton production in collisions of heavy nuclei at the CERN/SPS seemsExpand
Collective flow in heavy-ion collisions for E{sub lab}=1-160 GeV/nucleon
Collective transverse flow in heavy-ion collisions at incident energies E{sub lab}{approx_equal}(1-160)A GeV is analyzed within the model of three-fluid dynamics (3FD). Simulations are performed withExpand
Effects of nuclear absorption on the antiLambda/antiproton ratio in relativistic heavy ion collisions
An enhanced antiLambda/antiproton ratio in heavy-ion relative to p+p collisions has been proposed as one of the signatures for the Quark-Gluon Plasma (QGP) formation. A significantly largeExpand
Dynamical freeze-out in three-fluid hydrodynamics
The freeze-out procedure accepted in a model of three-fluid dynamics is analyzed. This procedure is formulated in terms of drain terms in hydrodynamic equations. The dynamics of freeze-out isExpand
The quantum damped harmonic oscillator
Abstract Starting with the quantization of the Caldirola–Kanai Hamiltonian, various phenomenological methods to treat the damped harmonic oscillator as a dissipative system are reviewed in detail. WeExpand
Quasi-coherent states for harmonic oscillator with time-dependent parameters
In this study, we discuss the harmonic oscillator with the time-dependent frequency, ω(t), and the mass, M(t), by generalizing the holomorphic coordinates for the harmonic oscillator. In generalExpand
