Neutron electric dipole moment in a supersymmetric model with singlet quarks

Yoshiya Takeda, Isao Umemura, Katsuji Yamamoto +1

The neutron electric dipole moment is investigated in a supersymmetric electroweak model admitting ${\mathrm{SU}(2)}_W$ singlet and $Q=-1/3$, say $D$-type, quarks. Significant $…
