QCD matter and properties change significantly around the chiral crossover temperature, and so far the effects on chiral observables and thermodynamical quantities have been studied with much care.
Here I present the screening spectrum for light hadrons, which includes chiral partners of mesons as well as different nucleon operators and their parity partners.
Measurements are done with two flavors of chirally symmetric domain-wall fermions at temperatures above the critical one, for different volumes and quark-masses.
Emergent SU(4) and SU(2)_CS symmetries will be discussed, as well as their implications.
