Description
Modifications in magnitude of fluctuations for different observables
are an excellent probe of a phase transition or its remnant.
In heavy-ion collision, fluctuations related to conserved charges
carried by light and strange quarks play an important role to identify
the QCD chiral crossover and deconfinement properties.
Recent Lattice QCD simulations have revealed that the charmed mesons
are deconfined together with light-flavor mesons in the temperature
range where the chiral symmetry is partially restored. This result
strongly suggests that the light-flavor dynamics interferes non-trivially
with the heavy flavors.
We discuss correlations between the light and heavy-light flavored
mesons at finite temperature within a chiral effective theory implementing
heavy quark symmetry. We show that the heavy quark dynamics is tied to
the light flavor physics, and the thermodynamics is strongly dragged by
the chiral crossover dominated by the non-strange flavors. Consequently,
the fluctuations carried by the states with strangeness can be used to characterize the onset of the chiral symmetry restoration.
