چکیده
|
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 n f = 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, = 53.1(9)( − 3 + 1 ) × 10− 10.
