  Reconnections between quantum vortex filaments in presence of trapped
particles are investigated using numerical simulations of the Gross--Pitaevskii
equation. Particles are described with classical degrees of freedom and modeled
as highly repulsive potentials which deplete the superfluid. First, the case of
a vortex dipole with a single particle trapped inside one of the vortices is
studied. It is shown that the reconnection takes place at the position of the
particle as a consequence of the symmetry breaking induced by it. The
separation rate between the reconnecting points is compatible with the known
dynamics of quantum vortex reconnections and it is independent of the particle
mass and size. After the reconnection, the particle is pushed away with a
constant velocity and its trajectory is deflected because of the transverse
momentum exchange with the vortex filaments. The momentum exchanges between the
particle, the vortex, and a density pulse are characterized. Finally, the
reconnection of two linked rings, each of them with several initially randomly
distributed particles is studied. It is observed that generically,
reconnections take place at the location of trapped particles. It is shown that
reconnection dynamics is unaffected for light particles.
