Kaon production has been studied in $\mathrm{Ni}+\mathrm{Ni}$ collisions at beam energies of 0.8--1.8 GeV/nucleon with the kaon spectrometer GSI. The ${K}^{+}$ cross section increases as ${E}_{\mathrm{beam}}^{5.3\ifmmode\pm\else\textpm\fi{}0.2}$. Both and ${K}^{\ensuremath{-}}$ mesons are predominantly produced central collisions. ${K}^{\ensuremath{-}}/{K}^{+}$ ratio measured equivalent below respective particle threshold is considerably larger for than nucleon-nucleon near threshold. This...
We report on first measurements of low-mass electron-positron pairs in Pb-Au collisions at the CERN SPS beam energy 40 AGeV. The observed pair yield integrated over range invariant masses 0.2<m</=1 GeV/c(2) is enhanced expectation from neutral meson decays by a factor 5.9+/-1.5(stat)+/-1.2(syst data)+/-1.8(syst decays), somewhat larger than previously higher 158 results are discussed with reference to model calculations based pi(+)pi(-)-->e(+)e(-) annihilation modified rho propagator. They...
We present a measurement of e+e− pair production in central PbAu collisions at 158AGeV/c. As reported earlier, significant excess the yield over expectation from hadron decays is observed. The improved mass resolution data set, recorded with upgraded CERES experiment CERN-SPS, allows for comparison different theoretical approaches. clearly favor substantial in-medium broadening ρ spectral function density-dependent shift pole mass. model implies that baryon induced interactions are key...
In the very heavy collision system $^{197}\mathrm{Au}$${+}^{197}$Au ${\mathit{K}}^{+}$ production process was studied as a function of impact parameter at 1 GeV/nucleon, beam energy well below free N-N threshold. The multiplicity increases more than linearly with number participant nucleons and ${\mathit{K}}^{+}$/${\mathrm{\ensuremath{\pi}}}^{+}$ ratio rises significantly when going from peripheral to central collisions. measured double differential cross section is enhanced by factor 6...
The azimuthal angular distribution of K+ mesons has been measured in Au + collisions at 1 AGeV. In peripheral and semi-central collisions, preferentially are emitted perpendicular to the reaction plane. strength anisotropy emission is comparable one pions. No in-plane flow was found for near projectile target rapidity.
Triple differential cross sections d3σ/dp3 for charged pions produced in symmetric heavy-ion collisions were measured with the KaoS magnetic spectrometer at synchrotron facility SIS GSI. The correlations between momentum vectors of and reaction plane 197Au+197Au an incident energy 1 GeV/nucleon determined. We observe, first time, azimuthally anisotropic distribution pions, enhanced emission perpendicular to plane. anisotropy is most pronounced high transverse semicentral collisions.Received...
Elliptic flow and two-particle azimuthal correlations of charged hadrons high-p(T) pions (p(T)>1 GeV/c) have been measured close to midrapidity in 158A GeV/c Pb+Au collisions by the CERES experiment. (v(2)) rises linearly with p(T) a value about 10% at 2 GeV/c. Beyond approximately 1.5 GeV/c, slope decreases considerably, possibly indicating saturation v(2) high p(T). Two-pion anisotropies for p(T)>1.2 exceed elliptic values 60% midcentral collisions. These nonflow contributions are...
We present results of a two-pion correlation analysis performed with the $\mathrm{Pb}+\mathrm{Au}$ collision data collected by upgraded CERES experiment in fall 2000. The was done bins reaction centrality and pion azimuthal emission angle respect to plane. source, deduced from data, is slightly elongated direction perpendicular plane, similarly as observed at Brookhaven National Laboratory Alternating Gradient Synchrotron Relativistic Heavy Ion Collider.
The Fourier harmonics, $v_2$ and $v_3$ of negative pions are measured at center-of-mass energy per nucleon pair $\sqrt{s_{\mathrm{NN}}}$= 17.3 GeV around midrapidity by the CERES/NA45 experiment CERN SPS in 0--30% central PbAu collisions with a mean centrality 5.5%. analysis is performed two bins as function transverse momentum $\mathrm{p_{\mathrm{T}}}$ from 0.05 GeV/$c$ to more than 2 GeV/$c$. This first measurement $v^{1/3}_{3}/v^{1/2}_{2}$ ratio energies. For above 0.5 GeV/$c$, nearly...
