Abstract: | It is argued that strong dynamics in the quark-gluon plasma and bound states of quarks and gluons is mostly due to nonperturbative
effects described by field correlators. The emphasis in the paper is made on two explicit calculations of these effects from
first principles—one analytic using gluelump Green’s functions and another using independent lattice data on correlators.
The resulting hadron spectra are investigated in the range T
c
≤ T < 2T
c
. The spectra of charmonia, bottomonia, light s
mesons, glueballs, and quark-gluon states calculated numerically are in general agreement with lattice MEM data. The possible
role of these bound states in the thermodynamics of quark—gluon plasma is discussed.
