Improved bounds on heavy quark electric dipole moments

Abstract

New bounds on the electric dipole moment (EDM) of charm and bottom quarks are derived using the stringent limits on their chromo-EDMs. The new limits, $|d_c|<1.5\times 10^{-21}e\text{cm}$ and $|d_b|<1.2\times 10^{-20}e\text{cm}$, improve the previous ones by about three orders of magnitude. These indirect bounds have implications for different models of new physics, including two-Higgs-doublet, leptoquarks, and supersymmetry models.
