Multiple Parton Interactions a different probe for hadron structure
abstract
Abstract:
The phenomenology of the Multiple Parton Interactions is reviewed with particular emphasis
on the most recent experimental progress at the Large Hadron Collider. The Multiple Parton
Interactions are responsible for a variety of phenomena affecting both common and rare
processes. They are invoked to describe the features of the generic interactions of small
systems (pp and pA) as well as those events with one order of magnitude larger multiplicity
where the well consolidated observation of long-range correlations still lacks of a widely
agreed interpretation. The study of the rare events characterised by two (or more) hard
interactions provides information on the hadronic matter distribution within the interacting
particles as well as on its correlation aspects. Taking into account the presence of this
additional source of Standard Model backgrounds, the so called Double Parton Scattering, is
also becoming unavoidable in view of the Very High Luminosity phase of the LHC.
