Lattice calculation of the leading strange quark-connected contribution to the muon g - 2

Lattice calculation of the leading strange quark-connected contribution to the muon g - 2
Lattice calculation of the leading strange quark-connected contribution to the muon g - 2
We present results for the leading hadronic contribution to the muon anomalous magnetic moment due to strange quark-connected vacuum polarisation effects. Simulations were performed using RBC--UKQCD's Nf=2+1 domain wall fermion ensembles with physical light sea quark masses at two lattice spacings. We consider a large number of analysis scenarios in order to obtain solid estimates for residual systematic effects. Our final result in the continuum limit is a(2)had,s?=53.1(9)(+1?3)×10?10.

Abstract

We present results for the leading hadronic contribution to the muon anomalous magnetic moment due to strange quark-connected vacuum polarisation effects. Simulations were performed using RBC--UKQCD's Nf=2+1 domain wall fermion ensembles with physical light sea quark masses at two lattice spacings. We consider a large number of analysis scenarios in order to obtain solid estimates for residual systematic effects. Our final result in the continuum limit is a(2)had,s?=53.1(9)(+1?3)×10?10.
