The NA52 strangelet search

The NA52 experiment searches for long-lived charged strangelets in 158 a GeV $c^{-1}$ Pb+Pb collisions at CERN SPS. The experiment is able to identify single particles coming from the collisions at $p_{t}$=0. We collected $10^{13}$ Pb+Pb interactions looking for negatively charged strangelets and $3...

Sumario:The NA52 experiment searches for long-lived charged strangelets in 158 a GeV $c^{-1}$ Pb+Pb collisions at CERN SPS. The experiment is able to identify single particles coming from the collisions at $p_{t}$=0. We collected $10^{13}$ Pb+Pb interactions looking for negatively charged strangelets and $3\times {10^{11}}$ Pb+Pb interactions for positively charged ones. No evidence for the production of strangelets has been observed. We present here resulting experimental differential and total upper production limits. (8 refs).
