Query: Electric dipole moments of neutron and heavy quarks c, t in CP violating
  $U(1)_X$SSM   We study and analyze the electric dipole moments (EDMs) of neutron and heavy
quarks c, t in a CP-violating (CPV) supersymmetric U(1) extension of the
standard model called $U(1)_X$SSM, whose local gauge group is $U(1)_X\times
SU(3)_C\times SU(2)_L \times U(1)_Y$. The contributions from the one loop
diagrams and the Weinberg operators are taken into account with the new
introduced CPV phases beyond the minimum supersymmetric standard model(MSSM)
being non-zero. Our numerical results show that in $U(1)_X$SSM the neutron EDM
can be smaller than its experimental upper bound $1.8\times10^{-26}$ e$\cdot$cm
without a small CPV phase. The magnitudes of EDMs of heavy quarks c and t can
reach $10^{-24}$ e$\cdot$cm. and $10^{-22}$ e$\cdot$cm respectively. This is
favorable to the study of CPV.
