On the velocity of moving relativistic unstable quantum systems

TL;DR

This paper reveals that the velocity of moving relativistic quantum unstable systems cannot remain constant over time, due to fundamental quantum principles, affecting their decay behavior.

Contribution

It demonstrates a novel quantum effect where the velocity of unstable systems varies over time, contrasting with classical and stable quantum objects.

Findings

Velocity of unstable systems is not constant in time.

Quantum effects influence decay laws of moving unstable systems.

Fundamental principles cause velocity variation in relativistic quantum systems.

Abstract

We study properties of moving relativistic quantum unstable systems. We show that in contrast to the properties of classical particles and quantum stable objects the velocity of moving freely relativistic quantum unstable systems can not be constant in time. We show that this new quantum effect results from the fundamental principles of the quantum theory and physics: It is a consequence of the principle of conservation of energy and of the fact that the mass of the quantum unstable system is not defined. This effect can affect the form of the decay law of moving relativistic quantum unstable systems.
