Tachyon Behavior Due to Mass-State Transitions at Scattering Vertices

Abstract

A particle beam-thin foil scattering model is updated within the context of parametrized relativistic quantum theory (pRQT). This paper focuses on the creation, annihilation, and detection of tachyons when a beam of particles scatters off a thin foil. Improved calculation procedures and recent data are used to update model calculations for a pion-proton system.

A Transformation Factor for Superluminal Motion That Preserves Symmetrically the Spacetime Intervals

“…One of the major challenges associated with tachyons is their predicted imaginary rest mass [3,7], which would violate causality and lead to paradoxes. However, other theorists [1,7,10] have argued that their rest mass is a real value, for which they proposed various explanations. For instance, Caligiuri [7] has developed a novel relativistic quantum model that does not require an imaginary value for the mass, while Chodos [11] has suggested a new symmetry principle.…”

“…Fanchi [1] categorized particles based on their velocities. First, bradyons are particles with subluminal velocities and real rest mass, such as protons.…”

“…The existence of these superluminal particles is still a matter of debate in the physics community, although their existence is not forbidden by the STR [1,6]. Some authors argue that tachyons could violate the principle of macroscopic causality [7], whereas others believe they may not [8,9].…”

Parametrized Relativistic Quantum Theory in Curved Spacetime

“…The formulation is applied in Section 4 to a free scalar particle in flat spacetime. Section 4 includes a discussion of the mass of a particle and shows that both tardyons and tachyons have real mass in pRQT [6]. The pRQT formulation is then applied to a particle moving in Schwarzschild metric in Section 5.…”
