AbstractIf the c quark has an anomalous color-electric dipole moment (CEDM), it may serve as a new source of CP violation. The strength of such a CP violation depends on the size of the CEDM, d(c)'. We propose two effective ways of testing it from the large sample of psi' -> J/psi + pi(+) + pi(-) at the Beijing Spectrometer, and the obtained result, vertical bar d(c)'vertical bar < 3 x 10(-14) e cm (95% confidence level), gives the first experimentally determined upper bound on the CEDM of the c quark.
