The LHCb detector, thanks to its unique coverage of the forward region of pseudorapidity from 2 to 5, together with high-precision tracking and excellent particle identification, is a universal tool allowing to study a wide spectrum of QCD processes. The present document focuses on the recent results on the production of charged hadrons within jets recoiling against a Z boson at √s = 8 TeV as well as the Bose-Einstein correlations of same-sign pions at √s = 7 TeV, both performed using large samples of proton-proton collision data accumulated with the LHCb detector. The results on Central Exclusive Production at √s = 13 TeV based on new forward shower counters installed upstream and downstream of the LHCb detector are also discussed.
