1956 Nucl. Physics 1 622 The classification of the weak interactions is not satisfactory as yet. An attempt was made to extend isobaric spin conservation also to these, by introduction of a ‘particle’ that would carry no energy or momentum, no angular momentum or charge, but only ½ unit of isobaric spin (the ‘spurion’).

1983 Nucl. Physics B. 222 280 We must deal with diagrams which involve spurions of more than one type.

2010 P. Langacker Standard Model & Beyond iii. 150 It is sometimes useful to introduce a spurion,..used as a bookkeeping device.
