The Particle Listings 2000 edition gave the recommended value of antiproton mass, for the first time, to be within5 × 10−7in the relative deviation from the proton mass; this can be a test of theCPTinvariance. The value was derived by our precision 3-body calculation, using the ...

Here we report on a new comparison of the proton/antiproton charge-to-mass ratios with a fractional uncertainty of 16 parts per trillion. Our result is based on the combination of four independent long-term studies, recorded in a total time span of 1.5 years. We use different ...

The number of pions that interact with the nucleus is predominantly determined by simple geometric factors, such as the proximity of the annihilation point to the nuclear surface and the size (mass) of the nucleus. The number of surviving, and detectable pions which are not absorbed by the ...
