another term for kaon

  • ‘And observing a decay mode with a branching ratio on the order of 3E - 11 requires a prodigious number of K-mesons in order to achieve the desired sensitivity.’
  • ‘The surprising feature, however, was something that was not seen: the neutral K-meson was never seen to decay into an electron and a positron.’
  • ‘The number of these was small, about 0.3% of all decays, but has been confirmed in many experiments involving neutral K-mesons.’
