Abstract
Abstract
We argue that the difference in the yield ratio
measured in Au+Au collisions at
= 200 GeV and in Pb-Pb collisions at
= 2.76 TeV is mainly owing to the different treatment of the weak decay contribution to the proton yield in the Au+Au collisions at
= 200 GeV. We then use the coalescence model to extract from measured
the information about the
and nucleon density fluctuations at the kinetic freeze-out of heavy-ion collisions. We also show, using available experimental data, that the yield ratio
is a more promising observable than
for probing the local baryon-strangeness correlation in the produced medium.
