Answer:
marek gazdzicki -lrb- born 9 june 1956 -rrb- is a polish high-energy nuclear physicist , and the initiator and spokesperson of the na61/shine experiment at the cern super proton synchrotron -lrb- sps -rrb- .he , along with mark i. gorenstein , predicted the threshold energy of the quark -- gluon plasma production -lrb- the so-called '' onset of deconfinement '' -rrb- in high energy nucleus-nucleus collisions .these predictions have been confirmed by the na49 experiment at the cern sps within the energy scan programme which was started by him and peter seyboth .
