  The LHC experiments have reported new results with respect to the dynamics of
the strong interactions in $pp$, $p$A, and AA collisions over the past years.
In proton-proton collisions, the data analyses have focused in exploring the
nature of underlying events and double parton scattering at high energies. For
large systems, the heavy-ion collisions have provided new insights on physics
aspects related to azimuthal correlations, jet quenching, and particle
production, such as antiprotons. This Letter reports the recent results from
the ATLAS, CMS, and LHCb Collaborations on these various topics and highlights
its relevant findings for the high-energy community.
