A relativistic interpretation of the spin

Abstract

This paper aims at studying the spin once again. The departure point is thus the Stern and Gerlach experimental results that can be described in a coherent way in the frame of quantum mechanics only. Instead, the relativistic mechanics point of view is proposed here following the work presented in a previous article about rigid body rotation. Indeed, a careful study of the horizon of this relativistic rigid body rotation appears to be invariant from any observation angle in full agreement with the spin property
