Experimental Consequences for Conservation

Since the channel is dominated by the I=1 amplitude, we can assume . Using the CPLEAR values for and (obtained by fixing to ), we obtain for the phase difference:

which has a precision of one order of magnitude better than using the PDG values. Together with the world average value of the phase of the violating parameter , , we obtain the following limit for a possible violation:

This might be translated in a limit of the mass difference (assuming no violation in the decay amplitudes) using:

which is several orders of magnitude better then existing limits for other particles: but still two orders of magnitude away from a possible effect at the planck scale:

Some information about CPT violation in the I=0 decay amplitude can be obtained by comparing with the semileptonic charge asymmetry ( and assuming no CPT violation in the semileptonic decay amplitudes for the moment:

Using the PDG values, and , we find for a possible decay width difference:
