Description
There is strong evidence that the Standard Model of particle physics is
incomplete. The lack of evidence for any new particles had renewed
interest in theories postulating the existence of a Dark Sector. The
precise manifestation of these particles is entirely unknown, but at low
masses a dominant decay channel would be into a dimuon pair. To that
end, a search for a dark sector particle, $\chi$, is performed by
studying the decay $B^0 \rightarrow K^*(892)^0\mu^+\mu^-$ and $B^+ \rightarrow K^+\mu^+\mu^-$
for candidates consistent with $\chi \rightarrow \mu^+\mu^-$.
Limits on the branching fraction of both decay modes are set, as
functions of both the mass and \chi lifetime, in a fully frequentist manner.
