The LHCb detector, owing to its unique acceptance coverage (2 < η < 5) and a precise track and vertex reconstruction, is a universal tool allowing the study of various aspects of electroweak and QCD processes, such as particle correlations or Central Exclusive Production. The recent results on the measurement of the inelastic cross section at √s = 13 TeV as well as the Bose-Einstein correlations of same-sign pions and kinematic correlations for pairs of beauty hadrons performed using large samples of proton-proton collision data accumulated with the LHCb detector at √s = 7 and 8 TeV, are summarized in the present proceedings, together with the studies of Central Exclusive Production at √s = 13 TeV exploiting new forward shower counters installed upstream and downstream of the LHCb detector. The results provide a valuable insight into the high-energy hadronic interactions in the forward region at the LHC.
