Incoherent Photoproduction of $\phi$ Mesons in Ultra-Peripheral Pb+Pb Collisions at $\sqrt{s_{NN}}$ = 5.02 TeV
… $\phi$ meson in the $K^+ K^-$ decay channel in Pb+Pb collisions at an energy of 5.02 TeV per nucleon. We observed 23$\pm$5 $\phi$ meson candidates in the mass range 1.015 to 1.2 GeV/$c^2$. Efficiency correction was done with the STARLIGHT Monte Carlo. The efficiency-corrected mass distribution …

Measurements of Lambda, Lambda-bar and K-short from Pb-Pb collisions at 158 GeV per nucleon in a large acceptance experiment
… able to measure hadronic production in central Pb+Pb collisions. It uses a Pb beam, of energy 158 GeV per nucleon, from the CERN SPS with a fixed Pb target. The experiment features four large tracking detectors which can measure the trajectories of charged particles. In this thesis the method of …

Chemostratigraphic correlation and Pb-Pb dating of carbonate sequences in the external Gariep belt and Kango inlier of the Saldania belt in Namibia and South Africa
Worldwide most Neoproterozoic sequences are characterised by an intimate association of glaciogenic diamictite with marine carbonate deposits, indicating possibly rapid climatic changes from icehouse to greenhouse conditions. Such sequences also occur in the Pan-African Gariep Belt and in the Kango …
