Strangeness Production in Relativistic Heavy Ion Collisions
The aim of the experimental program of relativistic heavy ion collisions is to the study nuclear matter under extreme conditions of temperature and energy density. In order to achieve this goal, is necessary to understand the dynamics of such collisions. The most striking feature of relativistic heavy ion collisions is the copious production of particles of a great variety of species. The compr...
متن کاملStrangeness production in proton - proton and proton - nucleus collisions ∗
In these lectures we discuss the investigation of the strange meson production in protonproton (pp) and in proton-nucleus (pA) reactions within an effective Lagrangian model. The kaon production proceeds mainly via the excitations of N(1650), N(1710), and N(1720) resonant intermediate nucleonic states, in the collision of two initial state nucleons. Therefore, the strangeness production is expe...
متن کاملStrangeness and Antibaryon Production in Heavy-Ion Collisions
We review the experimental results on strangeness and antibaryon production in heavy-ion collisions at the AGS and SPS. We argue that the observed enhancement in kaon production at the AGS is consistent with hadronic description, while the multistrange baryon and antibaryon results at the SPS may need physics beyond hadronic nature. We call the need for measurements of low energy antilambda-pro...
متن کاملStrangeness in Nuclear Collisions
Data on the mean multiplicity of strange hadrons produced in minimum bias proton– proton and central nucleus–nucleus collisions at momenta between 2.8 and 400 GeV/c per nucleon have been compiled. The multiplicities for nucleon–nucleon interactions were constructed. The ratios of strange particle multiplicity to participant nucleon as well as to pion multiplicity are larger for central nucleus–...
متن کاملSelf-similarity of strangeness production in pp collisions at RHIC
New experimental data on transverse momentum spectra of strange particles (K S ,K −,K∗, φ, ...) produced in pp collisions at √ s = 200 GeV obtained by the STAR and PHENIX collaborations at RHIC are analysed in the framework of z-scaling approach. Scaling properties of the data z-presentation are illustrated. Self-similarity of strange particle production is discussed. A microscopic scenario of ...
