spurion, n. Particle Physics.|ˈspjʊərɪən| [a. G. Spurion (Dürr & Heisenberg 1961, in Zeitschr. f. Naturforsch. A. XVI. 726): see spurious a., -on1 1 a.] Any hypothetical subatomic particle introduced to facilitate mathematical calculations but having no physical reality (orig. one with isospin ½ and hypercharge {pm} 1).
1961Zeitschr. für Naturforsch. A. XVI. 726 The results of the calculations may be interpreted by describing the strange particles as composed of ordinary particles and a ‘spurion’ taken from the groundstate ‘vacuum’. 1963Nuovo Cimento XXVIII. 133 These ‘bosons’ do not have any Lorentz properties, i.e. mass and spin... They are called ‘spurions’ because of their similarity to the particle introduced by Wentzel, D'Espagnat and Prentki in connection with weak interactions. 1983Nucl. Physics B. CCXXII. 280 We must deal with diagrams which involve spurions of more than one type. 1986P. C. West Introd. Supersymmetry & Supergravity xviii. 194 We will..use the spurion technique to investigate the divergence induced by soft terms. |
