It is shown that all predictions for the light scalars, based on their four-quark nature, are supported by experiment. The future research program is outlined also.
We consider the possibility of representing the perturbative series for renormalization group invariant quantities in QCD in the form of their decomposition in powers of the conformal anomaly $\beta(\alpha_s)/\alpha_s$ in the \msbar-scheme. We remind that such expansion is possible for the Adler function of the process of $e^+e^-$ annihilation into hadrons and the Bjorken polarized sum rule...
A review of the main elements of (fractional) analytical QCD is
presented. The main part of the review is focused on the introduction of the Shirkov-Solovtsov and Bakulev-Mikhailov-Stefanis approaches and their recent extension beyond the leading order of perturbation theory. We present various representations in Euclidean and Minkowski spaces,
details of their construction and show their...
We report on some non-trivial results in the domain of chiral transport, that have been recently obtained, and that seems to us today to be significant. We pay considerable attention to the relationship between chiral effects and corresponding anomalies. We show non-universality of this dependence using examples of chiral separation and chiral vortical effects.
