Autor: Z. Fodor, C. Hoelbling, S.D. Katz, L. Lellouch, A. Portelli, K.K. Szabo, B.C. Toth

Publikováno v: Physics Letters B, Vol 755, Iss , Pp 245-248 (2016)

Electromagnetic effects are increasingly being accounted for in lattice quantum chromodynamics computations. Because of their long-range nature, they lead to large finite-size effects over which it is important to gain analytical control. Nonrelativi

Leading hadronic contribution to the muon magnetic moment from lattice QCD

The standard model of particle physics describes the vast majority of experiments and observations involving elementary particles. Any deviation from its predictions would be a sign of new, fundamental physics. One long-standing discrepancy concerns

While electromagnetic and up-down quark mass difference effects on octet baryon masses are very small, they have important consequences. The stability of the hydrogen atom against beta decay is a prominent example. Here we include these effects by ad
