$B$ decay anomalies and dark matter from strong dynamics

TL;DR

This paper proposes a model where leptoquarks explaining B decay anomalies are bound states from a new strong hypercolor interaction, with the lightest neutral state serving as a potentially detectable asymmetric dark matter candidate.

Contribution

It introduces a novel strong dynamics model linking B decay anomalies with dark matter, featuring a bound state leptoquark and a detectable dark matter candidate.

Findings

Leptoquarks as bound states from a new confining hypercolor interaction.

The lightest neutral bound state as an asymmetric dark matter candidate.

Potential for direct detection via magnetic dipole interactions.

Abstract

Indications of lepton flavor universality violation in semileptonic $B$ decays to $K$ or $K^*$ and muons or electrons can be explained by leptoquark exchange. I present a model in which the leptoquark is a bound state of constituents charged under a new confining SU($N_{\rm HC}$) hypercolor interaction. The lightest neutral bound state in the theory is an asymmetric dark matter candidate, that might be directly detectable through its magnetic dipole moment interaction.
