Test of charge-conjugation invariance in pp interactions Academic Article uri icon


  • Using pp interactions at s=5.44 GeV we have tested for evidence of C noninvariance through a comparison of the transverse-momentum distributions of particle and antiparticle produced at 90in the center of mass. We found an average charge asymmetry for pions with p between 0.5 and 2.7 GeV/c of =(N+-N-)(N++N-)=0.0060.009. This corresponds to a limit on the magnitude of the C-violating (relative to C-conserving) amplitude of Re0.0045. 1978 The American Physical Society.
