Global symmetries, hidden sectors and emergent (dark) vector interactions

TL;DR

This paper explores how hidden sectors coupled to the Standard Model can produce emergent dark vector particles through UV interactions, which differ from traditional fundamental dark photons, with insights motivated by AdS/CFT principles.

Contribution

It introduces a general framework for emergent dark vectors from hidden sectors and analyzes their properties, expanding beyond the conventional dark photon models.

Findings

Emergent vectors arise from UV interactions among currents or charged fields.

These vectors can be fundamentally different from traditional dark photons.

The study provides a broad theoretical foundation for hidden sector-induced vector phenomena.

Abstract

Hidden theories coupled to the SM may provide emergent (dark) vectors, that are composites/bound-states of the hidden fields. This is motivated by paradigms emerging from the AdS/CFT correspondence but it is a more general phenomenon. We explore the general setup and find that UV interactions among currents or charged fields give rise to emergent vectors in the IR. We study the general properties of such vectors and argue that they can be generically different from fundamental dark photons that have been studied so far.
