The Peskin-Takeuchi parameter and vector meson decay constants in QCD
Yasumichi Aoki, Tatsumi Aoyama, Ed Bennett +7
We use lattice gauge theory to investigate the Peskin-Takeuchi S parameter in SU(3) gauge theory with eight light fundamental fermions (eight-flavor QCD), a candidate for walking t…

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…
