Lattice QCD Studies of the Leading Order Hadronic Contribution to the Muon
Anthony Francis, Vera Gülpers, Gregorio Herdoíza +6
The anomalous magnetic moment of the muon, , is one of the most promising observables to identify hints for physics beyond the Standard Model. QCD contributions are currentl…
Study of the Couplings of QED and QCD from the Adler Function
Anthony Francis, Gregorio Herdoíza, Hanno Horch +3
The contribution from hadronic vacuum polarisation effects is responsible for a large fraction of the theoretical uncertainty in the running of the QED coupling. The current level…
The leading disconnected contribution to the anomalous magnetic moment of the muon
Anthony Francis, Vera Gülpers, Benjamin Jäger +3
The hadronic vacuum polarization can be determined from the vector correlator in a mixed time-momentum representation. We explicitly calculate the disconnected contribution to the…
Search for a bound H-dibaryon using local six-quark interpolating operators
Jeremy Green, Anthony Francis, Parikshit Junnarkar +3
We present early results from a lattice QCD study seeking a bound -dibaryon using flavors of improved Wilson fermions and a quenched strange quark. We compute a m…
Study of the anomalous magnetic moment of the muon computed from the Adler function
Michele Della Morte, Anthony Francis, Gregorio Herdoiza +5
We compute the Adler function on the lattice from vacuum polarization data with twisted boundary conditions using numerical derivatives. The study is based on CLS ensembles with tw…
The leading hadronic contribution to (g-2) of the muon: The chiral behavior using the mixed representation method
Anthony Francis, Vera Guelpers, Gregorio Herdoiza +4
We extend our analysis of the leading hadronic contribution to the anomalous magnetic moment of the muon using the mixed representation method to study its chiral behavior. We pres…
