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…
Isospin-breaking effects in inclusive hadronic data for the muon from first principles
Mattia Bruno, Taku Izubuchi, Christoph Lehner +3
The knowledge of isospin-breaking effects in hadronic decays is required for a high-precision determination of the Hadronic-Vacuum-Polarization contribution to from…
Lattice Calculation of Short-Range Contributions to Neutrinoless Double-Beta Decay at Physical Pion Mass
Peter Boyle, Felix Erben, Xu Feng +7
Neutrinoless double-beta () decays provide an excellent probe for determining whether neutrinos are Dirac or Majorana fermions. The short-range matrix elements associated…
Improvement in Autocorrelation Times Measured by the Master-Field Technique using Field Transformation HMC in 2+1 Domain Wall Fermion Simulations
Shuhei Yamamoto, Peter Boyle, Taku Izubuchi +3
The Field-Transformation Hybrid Monte-Carlo (FTHMC) algorithm potentially mitigates the issue of critical slowing down by combining the HMC with a field transformation, originally…
Hadronic light-by-light contribution to the muon anomaly from lattice QCD with infinite volume QED at physical pion mass
Thomas Blum, Norman Christ, Masashi Hayakawa +5
The hadronic light-by-light scattering contribution to the muon anomalous magnetic moment, )/2, is computed in the infinite volume QED framework with lattice QCD. We report $…
