Causal propagation for ELKO fields

TL;DR

This paper investigates the causal propagation of ELKO spinor fields, demonstrating that their propagation problem is always solvable, which advances understanding of their theoretical consistency.

Contribution

It provides a general analysis of causal propagation for ELKO fields, establishing their causal behavior as always solvable, a novel result in spinor field theory.

Findings

Causal propagation for ELKO fields is always solvable.

The analysis applies broadly to ELKO spinor fields.

Supports the theoretical consistency of ELKO as a spinor field model.

Abstract

We shall consider the general problem of causal propagation for spinor fields, focus attention in particular on the case constituted by ELKO fields and will show that the problem of causal propagation for ELKO fields is always solvable.
