英语词汇“omega minus”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

c. In full omega minus. A negatively charged hyperon with a mass of 1672 MeV that decays via the weak interaction into either a xi particle and a pion or a lambda particle and a kaon. Frequently written Ω⁻.The omega minus has strangeness of −3, zero isospin, spin of 3/2, and positive parity. It was predicted by the theory of the eightfold way, and its discovery in 1964 was important in the development of the concept of quarks.

1962 M. Gell-Mann in Proc. Internat. Conf. High-energy Physics 805/2 Starting with the resonance at 1238 MeV, we may conjecture that the Y₁*, at 1385 MeV and the Ξ* at 1535 MeV might belong to this supermultiplet... If J = 3/2⁺ is really right for these two cases, then our speculation might have some value and we should look for the last particle, called, say, Ω⁻ with S = −3, I = 0.

1964 Physical Rev. Lett. 12 204/1 The multitude of resonances which have been discovered recently..can be arranged as a decuplet with one member still missing... This particle (which we shall call Ω⁻, following Gell-Mann) is predicted to be a negatively charged isotopic singlet with strangeness minus three.

1964 Listener 30 Apr. 711/1 The new theory [of unitary symmetry] has made one striking prediction which was subsequently found to be correct: the observation of the negatively charged Omega particle.

1972 Daily Colonist (Victoria, Brit. Columbia) 24 Feb. 5/2 The physicists hope to make the first observation of ‘quarks’..by studying the activity of a rare and elusive sub-atomic particle called the omega-minus.

1974 H. Frauenfelder & E. M. Henley Subatomic Physics i. 6 The negative kaon..collides with a proton and produces a positive kaon, a neutral kaon, and an omega minus. The Ω⁻ decays into a Ξ⁰ and a π⁻.

1993 N.Y. Rev. Bks. 21 Oct. 78/3 The Higgs is not to be just another of the long list of successfully predicted particles, like the positron, omega-minus, neutrino, anti-proton, or tau-particle.
