TL;DR: In this paper, a simple nonperturbative model is used to estimate corrections to the first-order perturbation-theory formula for the isobaric multiplet masses.
Abstract: A simple nonperturbative model is used to estimate corrections to the first-order perturbation-theory formula for the isobaric multiplet masses. The leading-order correction to the equation, which is proportional to $T_{z}^{}{}_{}{}^{3}$, is found to be much smaller than expected from second-order perturbation arguments and from limits set by experiments.

TL;DR: In this paper, the formulae describing the radiative decays in QCD beyond the chiral limit are derived, and the modifications of the conventional PCAC formula due to the gluonic contribution to the axial anomaly in the flavour singlet channel are precisely described.
Abstract: The formulae describing the radiative decays $\eta'(\eta)\rta\c\c$ in QCD beyond the chiral limit are derived. The modifications of the conventional PCAC formulae due to the gluonic contribution to the axial anomaly in the flavour singlet channel are precisely described. The decay constants are found to satisfy a modified Dashen formula which generalises the Witten--Veneziano formula for the mass of the $\eta'$. Combining these results, it is shown how the topological susceptibility in QCD with massive, dynamical quarks may be extracted from measurements of $\eta'(\eta)\rta\c\c$.

TL;DR: In this article, the authors examined the Smarr formula in eleven-dimensional spacetime compactified on a general six-dimensional Ricci-flat manifold and showed that non-zero mass for smooth and horizonless solutions can only be provided by cohomology.
Abstract: We examine the Smarr formula in eleven-dimensional spacetime compactified on a general six-dimensional, Ricci-flat manifold. We show that non-zero mass for smooth and horizonless solutions can only be provided by cohomology. Furthermore, we confirm the result that there are no solitons without topology and prove the fact that Chern-Simons terms in the mass formula only appear in order to generate a purely topological integral.
