Superluminal motion and Lorentzian symmetry breaking and repairing in two-metric theories

TL;DR

This paper discusses how two-metric theories can potentially explain superluminal neutrinos while maintaining Lorentzian symmetry and causality, offering a novel approach to reconcile experimental claims with fundamental physics.

Contribution

It introduces a method within two-metric theories to restore Lorentzian symmetry without violating causality in the context of superluminal particles.

Findings

Proposes a two-metric framework for superluminal neutrinos

Shows Lorentzian symmetry can be maintained without causality violation

Provides a theoretical basis for superluminal motion consistent with relativity

Abstract

The new results by OPERA collaboration claim the discovery of superluminal neutrinos. Superluminal particles have to break Lorentzian symmetry or causality principle. The method discussed gives us the possibility to reintroduce Lorentzian symmetry without breaking of causality.
