  We study the prospects for observing double parton scattering through
four-muon final states, forming two opposite-sign muon pairs, in the LHCb
experiment in pp collisions at 14 TeV centre of mass energy. We consider two
special cases, namely double Drell-Yan and J/psi-pair production. The kinematic
properties and prospects for observing these processes are discussed. We find
that the production rate depends strongly on the origin of the four muons,
while many kinematic properties can be used to help identify the presence of
double parton scattering events.
