  8. Actually, in ref. (6),16 A, 208 (1973);E. Recami andR. Mignani: preprint ITF, Kiev (to appear); an in preparation. it is shown that the notion of «antiparticle» is apurely relativistic one, in the sense that it may be derived within the mere framework of special relativity (together with the concept of «charge coniugation»Ĉ; here «charge» enters with its widest meaning).

  9. It must be taken into account that time-reversal implies also velocity-reversal (v»−v) and impulse-reversal (p»−p). However, the combined operationTE implies still velocity-reversal butno longer impulse-reversalp (since energy-reversal means of course relativistic-mass-reversal).

  10. Analogously, if we go on comprehensively considering both co-ordinate and momentum spaces, operationPT actually means operationPpTE, which results in aCPT operation.

  12. By the way, energy conservation holds of course also in generalized relativity theory, since covariance under time translations is still required even in the presence of tachyons and of Superluminal reference frames. See ref. (6).
