Evaluation of the three-flavor quark-disconnected contribution to the muon anomalous magnetic moment from experimental data ” by S. Peris, M. Golterman (IFAE visitor) and collaborators has been published at Physical Review D. The article is highlighted as an Editor’s Suggestion.

From the journal:

“Theory predictions for g-2, the muon’s anomalous magnetic moment, can be made with dispersive methods or with lattice calculations, but some current estimates show tension between the two. This becomes especially important in view of the apparent discrepancy with the experimental value. The authors of this Suggestion show how a subset of contributions to the hadronic vacuum polarization, the leading source of theory uncertainty, can be related to physical observables. The results can help isolate the disagreement between the differing calculations.”
