Query: $B$ decay anomalies and dark matter from strong dynamics   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.
