We re-estimate the tensor susceptibility of QCD vacuum, χ, and to this end, we re-estimate the leptonic decay constants for transversely polarized ρ, ρand b1-mesons. The origin of the susceptibility is analyzed using duality between ρand b1channels in a 2-point correlator of tensor currents. We confirm the results of [1] for the 2-point correlator of tensor currents and disagree with [2] on bot...

We study the mixed formulation of the stochastic Hodge–Laplace problem defined on an n-dimensional domain D (n 1), with random forcing term. In particular, we focus on the magnetostatic problem and on the Darcy problem in the three-dimensional case. We derive and analyse the moment equations, that is, the deterministic equations solved by the mth moment (m 1) of the unique stochastic solution o...

The magnetic dipole moments of the light tensor mesons f2, a2 and strange K∗0 2 (1430) tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic dipole moment for the charged tensor particles are considerably different from zero. These values are very close to zero for the light neutral f2 and a2 tensor mesons, while it has a sm...
