Search for strangeness abundant quark-gluon plasma in nucleus-nucleus collisions

Abstract

The experimental data on {Lambda} and K{sup 0} production in CC-, CNe-, ONe-, MgMg-collisions at E{sub p}=3.4-3.7 A GeV were analysed to study highly excited hadron matter and to search for QGP. It was found that with increasing of the number of nucleons-participants or their energy become more uniform up to nearly isotopic ones; the temperatures T{sub {Lambda},K} rise from 80 MeV up to 150-160 MeV. To explore a further energy dependence of the revealed effects, the above data were compared with the results, recently obtained at BNL and CERN. This comparison shows that T{sub {Lambda},K} as a function of E appears to remain nearly constant up to the highest energy of nuclei available at CERN until now (E{approx}6000 GeV) at which the strangeness enhancement (for {Lambda}, {Lambda}-tilde, K{sub S}{sup 0} with P{sub T}>0.4-0.5 GeV/c) was observed as well. 23 refs.; 5 figs.; 1 tab.
