Recent data on strange particle production in 4 GeV/c antiproton annihilations on Ta can be successfully interpreted if quark-gluon plasma formation is assumed along with a simple reaction model in which antiprotons deposit energy in the forward cone of nuclear matter within the target nucleus. The observed spectra and total abundances of lambdas and kaons are consistent with the hypothesis that (super cooled) quark matter phase has been formed at a rather modest temperature T≲60 MeV. The spectra can then be successfully interpreted both with reference to their form and relative abundance.
