Strange and charm HVP contributions to the muon (g − 2) including QED corrections with twisted-mass fermions

Abstract: We present a lattice calculation of the Hadronic Vacuum Polarization (HVP) contribution of the strange and charm quarks to the anomalous magnetic moment of the muon including leading-order electromagnetic corrections. We employ the gauge configurations generated by the European Twisted Mass Collaboration (ETMC) with N f = 2 + 1 + 1 dynamical quarks at three values of the lattice spacing (a 0.062, 0.082, 0.089 fm) with pion masses in the range M π 210-450 MeV. The strange and charm quark masses are tuned at the… Show more

“…Accurate lattice QCD results for the separate s-, c-and (negligible) b-quark connected contributions to a HVP,LO µ were first obtained in Refs [16][17][18]. Subsequent lattice QCD calculations [14,[19][20][21] using different methods and quark formulations are in excellent agreement with these results.…”

“…We believe that this additional data may facilitate cross-checks between different lattice collaborations in particular also with regard to the up and down quark connected contribution in the isospin limit. [42], Mainz 2017 [43], BMW 2017 [39], ETMC 2017 [45], RBC/UKQCD 2015 [29], and FNAL/HPQCD/MILC 2017 [46]. The innermost error-bar corresponds to the statistical uncertainty.…”

“…First efforts in this direction date back over two decades [2], and interest in this field has picked up considerably over the last few years. First results are now available, in particular, for spectral quantities [3][4][5][6][7][8][9][10][11][12][13][14][15][16], and progress is being made in matrix elements and scattering and decay amplitudes [17][18][19][20][21][22][23][24].…”
