Deep Antiproton Annihilations on Nuclei

  • Johann Rafelski


Hot nuclear matter can be created in annihilations on nuclei: the antiproton penetrates deep inside the nucleus and the available energy is shared by a small number of nucleons participating in the reaction1,2. I consider here in detail recent strange partiele production data obtained in 4 GeV/c Ta3,4 annihilations and present an analysis of the experimental results in terms of a hot blob of quark gluon plasma. In particular, the observed spectra and total abundances of lambdas and kaons are consistent5 with the hypothesis that (super cooled) quark matter phase has been formed at rather modest temperature T < 60 MeV.
