Classical particles with unusual properties

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

In addition to the ordinary subluminal particles (bradyons) and to the superluminal particles (tachyons), it seems to be possible to conceive the existence of other kinds of particles in the framework of classical special-relativity mechanics. They are neither bradyons nor tachyons in the usual sense of these words. The ones considered here are characterized by the assumption that their four-momentum is orthogonal to the four-velocity. Some of the kinematical and dynamical properties of these particles are discussed.

Riassunto

Oltre alle ordinarie particelle subluminali (bradioni) e alle particelle superluminali (tachioni), sembra possibile concepire l'esistenza di altri tipi di particelle nel quadro della meccanica classica della relatività speciale. Non sono nè bradioni nè tachioni nel senso usuale di questi termini. Quelle considerate qui sono caratterizzate dall'ipotesi che il loro quadrimpulso sia ortogonale alla quadrivelocità. Sono discusse alcune proprietà cinematiche e dinamiche di queste particelle.
