The radiative transitions between ground-states (GS) of light q bar q mesons are investigated in the U~(12)-scheme. In this scheme the rich decay-spectra are offered even in transition between GS due to the appearance of chiral states. As a…

We consider chiral perturbation theory in the meson sector at order $E^6$. In the terminology of the external field technique, the two--loop graphs so generated are of the sunset type. We discuss the evaluation of several of these in the…

In the presence of an $\Omega$-deformation, local operators generate a chiral algebra in the topological-holomorphic twist of a four-dimensional $\mathcal{N} = 2$ supersymmetric field theory. We show that for a unitary $\mathcal{N} = 2$…
