A look into the possibility of negative mass

TL;DR

This paper explores the theoretical plausibility and implications of negative mass particles within current physics, highlighting their potential necessity for symmetry and differences in quantum mechanics representations.

Contribution

It provides a theoretical analysis of negative mass particles, demonstrating their compatibility with physics and their role in symmetric models.

Findings

Negative mass particles are not prohibited by current physics.

In relativistic quantum mechanics, negative mass bispinors differ from positive mass ones.

Negative mass may be essential for symmetric physical theories.

Abstract

We investigate the possibility of negative mass particles and whether physics as we know it today allows or excludes their existence and what properties they might have in the light these laws. We show that nothing prohibit their existence, in the contrary, for a more symmetric world their existence is essential. In relativistic quantum mechanics, the negative mass bispinor in the rest frame takes a different form than the positive mass bispinor.
