Calculation of neutron electric dipole moment from Lattice QCD
Thomas Blum, Fangcheng He, Taku Izubuchi +3
Experimental constraints on the neutron electric dipole moment (nEDM) may imply strong-CP problem in QCD, or unnatural smallness of the QCD theta angle. In this work, we present a…
The Neutron Electric Dipole Moment from Lattice QCD using a Background Electric Field
Thomas Blum, Fangcheng He, Taku Izubuchi +3
We present the calculation of the neutron electric dipole moment (nEDM) using 2+1 flavor domain wall fermion ensembles with fixed lattice spacing a…
Progress on computing the hadronic vacuum polarization contribution to the muon anomalous magnetic moment with staggered fermions
Vaishakhi Moningi, Christopher Aubin, Thomas Blum +3
We give an update of our calculation of the light-quark, connected, hadronic vacuum polarization contribution to the muon anomalous magnetic moment, or muon . The update inclu…
The Light Quark Connected Hadronic Vacuum Polarization Contribution to the muon anomaly via Sparsened Meson Fields
Vaishakhi Moningi, Christopher Aubin, Thomas Blum +3
We present an update on our determination of the light-quark connected contribution to the hadronic vacuum polarization (HVP) of the muon anomalous magnetic moment, , on a fi…
Machine-learning techniques as noise reduction strategies in lattice calculations of the muon
Thomas Blum, Alessandro Conigli, Lukas Geyer +3
Lattice calculations of the hadronic contributions to the muon anomalous magnetic moment are numerically highly demanding due to the necessity of reaching total errors at the sub-p…
Toward inclusive observables with staggered quarks: the smeared ~ratio
Thomas Blum, William I. Jay, Luchang Jin +2
Inclusive hadronic observables are ubiquitous in particle and nuclear physics. Computation of these observables using lattice QCD is challenging due the presence of a difficult inv…
