Abstract

We present a new evaluation of the two-point function built from the colourless operators $g Ψ λ^{a} γ_{v} (γ_{5})ΨF^{μv}_{a}$ . Previous calculations for the dimension-six vacuum condensate contributions were incomplete. We give new predictions for the masses and decay amplitudes of 1⁻⁺ and 0⁻⁻ hermaphrodite mesons.

QCD spectral sum rules 2022
2023, Nuclear and Particle Physics Proceedings
We present a compact review of the status of QCD spectral sum rules until 2022. We emphasize the recent progresses for determining the QCD input parameters ( $α_{s}$ , running quark masses, quark and gluon condensates) where their correlations have been taken into account. Some selected phenomenological uses of the sum rules in different channels (light and heavy quarks, gluonia/glueballs, hybrids and four-quark states) are briefly reviewed and commented. The estimate of the $1^{- +}$ light hybrid mass is revised which confirms the hybrid nature of the $π_{1} (1600)$ but not the $π_{1} (2050)$ .
1<sup>- +</sup> light exotic mesons in QCD
2009, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
We systematically re-examine the extraction of the masses and couplings of the $1^{- +}$ hybrid, four-quark and molecule mesons from QCD spectral sum rules (QSSR). To NLO for the perturbative and power corrections, the hybrid mass is $M_{H} = 1.81 (6) GeV$ and $M_{H} ⩽ 2.2 (2) GeV$ from the positivity of the spectral function. In the same way, but to LO, the four-quark state mass is $M_{4 q} = 1.70 (4) GeV$ and $M_{4 q} ⩽ 2.4 (1) GeV$ , while the molecule mass is $1.3 (1) GeV$ . The observed $π_{1} (1400)$ and $π_{1} (1600)$ could be explained by a two-component mixing with the set of input masses (1.2–1.3; 1.70–1.74) GeV and with a mixing angle $θ ≃ - (11.7 \pm 2.2) °$ , which slightly favours a molecule/four-quark mixing, and which eventually suggests that the $π_{1} (2015)$ is mostly an hybrid meson. Isospin and non-exotic partners of the previous states and some of their radial excitations are also expected to be found in the energy region around 2 GeV. Further tests of this phenomenological scenario are required.

Present status of glueball searches
2000, Nuclear Physics A
The present status of experimental searches for glueballs is reviewed. A critical examination is made of the criteria used in the identification of glueballs. It is concluded that the mixing of glueball states with normal $q q$ states deprives us so far of any ‘smoking guns’, and at least two states, f₀(1500) and f₀(1710) remain viable contenders for the scalar (0⁺⁺) glueball. It is also shown that in the proton-antiproton annihilation experiments no evidence is found for the existence of ξ(2230), the much heralded candidate for the tensor glueball.
