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...
Squeeze-out, a component of the collective flow nuclear matter, is preferential emission particles out reaction plane. Using sphericity method out-of-plane/in-plane ratio kinetic energy has been analyzed as function multiplicity and beam for Ca+Ca, Nb+Nb, Au+Au collisions measured with Plastic Ball detector at Bevalac. Also, azimuthal distribution around axis are presented together extracted ratios. Finally, rapidity dependence investigated new using transverse momentum components particles.
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...
The Future Circular Collider (FCC) Study is aimed at assessing the physics potential and technical feasibility of a new collider with centre-of-mass energies, in hadron-hadron collision mode, seven times larger than nominal LHC energies. Operating such machine heavy ions an option that being considered accelerator design studies. It would provide, for example, Pb-Pb p-Pb collisions sqrt{s_NN} = 39 63 TeV, respectively, per nucleon-nucleon collision, integrated luminosities above 30 nb^-1...
We predict glueball/oddball resonances lying on the pomeron/odderon trajectories. A simple new form of trajectories, with threshold and asymptotic behaviour required by analyticity unitarity, is proposed. The parameters these (pomeron odderon) trajectories are fitted to data high-energy elastic proton-proton proton-antiproton scattering. extrapolated resonance region masses widths glueballs oddballs. may be used calculate processes central exclusive diffraction (CED).
