Particle Physics the exchange of an uncharged subatomic particle in an interaction between particles; (frequently attributive) designating an interaction mediated by such an exchange, in which there is no transfer of charge between the interacting particles. ΚΠ 1968 R. J. Oakes in Physical Rev. Lett. 20 1539/1 In this note we discuss how the neutral vector and axial-vector currents..can be used to construct a neutral current × current weak interaction. 1974 Sci. Amer. Dec. 108/2 The process is described as an interaction between two neutral currents, meaning that the interaction does not change the electric charge of the participating particles. 1987 D. H. Perkins Introd. High-Energy Physics (ed. 3) ix. 333 (caption) Weak and electromagnetic neutral-current couplings of electrons to quarks. 2000 Econ. & Philos. 16 58 For selecting the 290,000 bubble-chamber photographs taken at CERN during the experiments on weak neutral currents in 1973, non-experts were employed after a brief training. < as lemmas |
