摘要
It is proved that the n-twistor expression of a particle's four-momentum vector reduces, by a unitary transformation, to the two-twistor expression for a massive particle or the one-twistor expression for a massless particle. Therefore the genuine n-twistor description of a massive particle in four-dimensional Minkowski space fails for the case n >= 3. Published by AIP Publishing.
