Glueballs, Hybrids, Multiquarks. Experimental facts versus QCD inspired concepts
TL;DR: In this article, it was shown that the meson σ and κ mesons exhibit a spectrum of (squared) masses which are proportional to the sum of orbital angular momentum and radial quantum numbers.

Exploring improved holographic theories for QCD: part I
TL;DR: In this paper, a gravity theory in five dimensions coupled to a dilaton and an axion may capture the important qualitative features of pure YM theory, and a part of the effects of higher α'-corrections is resummed into a Dilaton potential, which determines the full structure of the vacuum solution.

Quark structure of pseudoscalar mesons
TL;DR: In this paper, the properties of pseudoscalar mesons can be understood in terms of the underlying quark (and eventually gluon) structure, and a thorough discussion of theoretical and phenomenological consequences of the mixing approach is given.

The Physics of Glueballs
TL;DR: In this article, a review of recent results in the physics of glueballs with the aim set on phenomenology and discuss the possibility of finding them in conventional hadronic experiments and in the Quark Gluon Plasma.

QCD and resonance physics. theoretical foundations
TL;DR: In this paper, a systematic study is made of the non-perturbative effects in quantum chromodynamics, where the basic object is the two-point functions of various currents and the terms of this series are shown to be of two distinct types.

TL;DR: In this article, the dispersion charmonium theory was extended to include power terms due to the nonperturbative effects of QCD, and an estimate for the gluonic vacuum expectation value was derived.

Current Algebra Theorems for the U(1) Goldstone Boson
TL;DR: In this paper, the U(1) problem is reconsidered from the point of view of the 1 N expansion, and it is argued that various heuristic ideas about the η′ are valid from this view.

U(1) without instantons
TL;DR: In this paper, the U(1) problem is shown to be consistent with expected θ dependences and anomalous Ward identities, if a modified Kogut-Susskind mechanism is used.
