      The strongly coupled phase of Yang-Mills plasma with gauge group SU(3) is studied in a Tmatrix approach. The existence of lowest-lying glueballs, interpreted as bound states of two transverse gluons (quasi-particles in a many-body setup), is analyzed in a non-perturbative scattering formalism with the input of lattice-QCD static potentials. The relevance of the singlet and the (colored) octet ...

    • Thermodynamics of the quark-gluon plasma within a T-matrix approachPeer reviewedOpen access

      Article scientifique
      The strongly coupled phase of the quark-gluon plasma (QGP) is studied here by resorting to a T -matrix formulation in which the medium is seen as a nonideal gas of quasiparticles (quarks, antiquarks, and gluons) interacting nonpertubatively. In the temperature range under study, (1–5)Tc, where Tc is the temperature of deconfinement, the interactions are expected to be strong enough to generate ...
