Gauge-invariant screening masses and static quark free energies in $N_f=2+1$ QCD at non-zero baryon density

Michele Andreoli, Claudio Bonati, Massimo D'Elia +4

We discuss the extension of gauge-invariant electric and magnetic screening masses in the Quark-Gluon Plasma to the case of a finite baryon density, defining them in terms of a mat…
