Strong correlations in hot QCD
"... After reviewing briefly the basic strategy of analyzing the RHIC data, recent lattice results of the nonpertubative/strongcoupling aspects of quarkgluon plasma probed primarily by the heavy quarks are presented. In particular, free energies of static quarks in various color channels, the Debye sc ..."

QCD simulations is also summarized. It is argued that the hot plasma above the (pseudo)critical temperature Tc is still strongly interacting up to T ∼ (1.5 − 2)Tc so that hadronic bound states or resonances made of strange, charm and bottom quarks in certain channels may survive inside the plasma
Strong Coupling QCD in the Continuum
, 2009
"... A short overview of studies of strong coupling problems in hadron physics is presented. The SchwingerDyson/BetheSalpeter approach in the continuum allows the perturbative regime to be connected to the world of strong coupling that controls confinement and chiral dynamics that in turn determines th ..."

Baryon resonances and strong QCD
, 2002
"... Abstract: Lightbaryon resonances (with u,d, and s quarks in the SU(3) classification) fall on Regge trajectories. When their squared masses are plotted against the intrinsic orbital angular momenta L, ∆ ∗ ’s with even and odd parity can be described by the same Regge trajectory. For a given L, nu ..."

require three particles to participate in the dynamics. This conflict is resolved by proposing that quarks polarize the QCD condensates and are surrounded by a polarization cloud shielding the color. A new interpretation of constituent quarks as colored quark clusters emerges; their interaction
JLABTHY9909 Flux Tube ZeroPoint Motion, Hadronic Charge Radii, and Hybrid Meson Production Cross Sections
, 1999
"... Flux tube zeropoint motion produces quark displacements transverse to the flux tube which make significant contributions to hadronic charge radii. In heavy quark systems, these contributions can be related by Bjorken’s sum rule to the rates for semileptonic decay to hybrid mesons. This connection c ..."

can be generalized to other leptoproduction processes, where transverse contributions to elastic form factor slopes are related to the cross sections for the production of the associated hybrid states. I identify the flux tube overlap integral responsible for these effects as the strong QCD analogue

Nonperturbative formulas for central functions of supersymmetric gauge theories
 Nucl. Phys. B
, 1998
"... For quantum field theories that flow between ultraviolet and infrared fixed points, central functions, defined from twopoint correlators of the stress tensor and conserved currents, interpolate between central charges of the UV and IR critical theories. We develop techniques that allow one to calcu ..."

IR> 0. This is new evidence in strongly coupled theories that this quantity satisfies a fourdimensional analogue of the ctheorem, supporting the idea of irreversibility of the RG flow. Various other implications are discussed. 1 1
STRONG HADRONIC DECAYS IN QCD2.
, 2000
"... Strong hadronic decays are discussed in the ’t Hooft model for the twodimensional QCD in the limit of infinite number of colours. Adler selfconsistency condition is derived for decays with pions in the final state and the corresponding amplitude is demonstrated to vanish identically in the chiral l ..."

Lattice QCD in strong magnetic fields
"... Vacuum of Quantum Chromodynamics in very strong (hadronscale) magnetic fields exhibits many interesting nonperturbative effects. Some of these effects can be studied with the help of lattice simulations in quenched QCD. We review our recent results demonstrating that very strong external magnetic ..."
