Description
The LHCb collaboration has recently reported on some anomalies in $b
\to s$ transitions. In addition to discrepancies with the Standard
Model (SM) predictions in some angular observables and branching
ratios, an intriguing hint for lepton universality violation was
found. Here we propose a simple model that extends the SM with a dark
sector charged under an additional $U(1)$ gauge symmetry. The
spontaneous breaking of this symmetry gives rise to a massive
$Z^\prime$ boson, which communicates the SM particles with a valid
dark matter candidate, while solving the $b \to s$ anomalies with
contributions to the relevant observables.
