Glueball Regge Trajectories
read the original abstract
We investigate the spectrum of glueballs in 3D and 4D SU(N) gauge theories. Our motivation is to determine whether the states lie on straight Regge trajectories. To this end we develop new lattice techniques to reliably determine the states carrying higher spin. It has been conjectured for a long time that glueballs are the physical states lying on the pomeron, the trajectory responsible for the slowly rising hadronic cross-sections at large centre-of-mass energy.

Glueballs, Constituent Gluons and Instantons
A two-gluon constituent model with instanton-induced mass and adjoint confinement predicts a compact scalar glueball of radius ~1/3 fm and an extended tensor state, matching quenched lattice results.

Two Lectures on the Phase Diagram of QCD
QCD features at least three phases at zero baryon density and three at high density, including a Quarkyonic phase at high density and low temperature, described via large-N_c and a parameter-free 3D string model.
