Antiproton annihilation in light nuclei

The possibility of antiproton annihilation on a cluster of nucleons is investigated. In the model, the annihilation forms a quark-gluon plasma droplet which on expansion coagulates into mesons and baryons. The energy spectra and multiplicities of mesons as well as kaon and lambda production ratios a...

Zusammenfassung:The possibility of antiproton annihilation on a cluster of nucleons is investigated. In the model, the annihilation forms a quark-gluon plasma droplet which on expansion coagulates into mesons and baryons. The energy spectra and multiplicities of mesons as well as kaon and lambda production ratios are computed. The probability of annihilation on a pair of nucleons is about ten percent, but the lower plasma temperature reduces strangeness production.
