On the Possible Observation of Mirror Matter

TL;DR

This paper investigates the theoretical possibility of mirror matter existing at TeV scales, its potential effects on neutrino magnetic moments, and the experimental signatures it could produce at colliders like the LHC.

Contribution

It introduces the idea that light mirror matter could influence neutrino properties and produce detectable collider signatures, bridging particle physics models with experimental tests.

Findings

Mirror matter could significantly enhance the tau neutrino magnetic moment.

Mirror matter may produce distinctive collider signatures at the LHC.

Small mixing with MSSM matter can have observable effects.

Abstract

The possibility that mirror matter with masses in the several hundred GeV- TeV range exists is explored. Mirror matter appears quite naturally in many unified models of particle interactions both in GUTs and in strings often in vector-like combinations. Some of these vector-like multiplets could escape acquiring super heavy masses and remain light down to the low energies where they acquire vector-like masses of electroweak size. It is found that a very small mixing of the vector-like multiplets with MSSM matter (specifically with the third generation matter) can produce very large contributions to the magnetic moment of the $\tau$ neutrino by as much as several orders of magnitude putting this moment in the range of accessibility of improved experiment. Further, it is shown that if mirror matter exists it would lead to distinctive signatures at colliders and thus such matter can be explored at the LHC energies with available luminosities.
