Weak decays of the vector and
mesons to the
final state provide novel potential to test the Standard Model of particle physics. Such processes have extremely small branching fractions as the vector mesons are able to decay through electromagnetic and (for the
meson) strong interactions. Nonetheless, the production of copious quantities of these particles in LHC collisions, and the ability to exploit experimental techniques that can suppress background to low levels, provides good potential to reach interesting sensitivity. The possibility to reconstruct these processes as part of the decay chain of
or
mesons appears particularly attractive due to the clean experimental signature of the displaced vertex. Indeed, published LHCb data on
decays already implies a stringent limit on the branching fraction of
. Estimates are made on the achievable sensitivity to
and
decays with the LHCb experiment.
