dc.description.abstract | First results on K/π, p/π and K/p fluctuations
are obtained with the ALICE detector at the CERN LHC
as a function of centrality in Pb–Pb collisions at √sNN =
2.76 TeV. The observable νdyn, which is defined in terms
of the moments of particle multiplicity distributions, is used
to quantify the magnitude of dynamical fluctuations of relative particle yields and also provides insight into the correlation between particle pairs. This study is based on a novel
experimental technique, called the Identity Method, which
allows one to measure the moments of multiplicity distributions in case of incomplete particle identification. The
results for p/π show a change of sign in νdyn from positive
to negative towards more peripheral collisions. For central
collisions, the results follow the smooth trend of the data at
lower energies and νdyn exhibits a change in sign for p/π and
K/p. | fi |
