Several LHC experiments exploit the high acceptance in the forward region. Most of them use the possibility of measuring the intact proton in an elastic event. This approach can enhance the purity of selecting jet-gap-jet events, leading to refined limits on photon-induced processes or to a better study of pion pair production. Diffraction and elastic scattering plays also the main role when measuring the $\varrho$-parameter or the nuclear slope in total cross-section measurements.

In this talk a summary of the latest results on this topic from the ATLAS, CMS and LHCb experiments has been presented.
