  Bose-Einstein correlations for same-sign charged pions and kinematic b-bbar
correlations in proton-proton collisions at a center-of-mass energy of 7 and 8
TeV are studied by the LHCb experiment. The dependence of Bose-Einstein
correlation parameters on the charged-particle multiplicity is investigated.
The correlation radius is observed to increase with multiplicity, while the
chaoticity parameter decreases. The b-bbar correlations are studied using
inclusive b quark decays to jpsi and are found to be in good agreement with
theoretical predictions.
