Self Organizing Maps Parametrization of Parton Distribution Functions

Introduction
⇒The study of hadron structure in the LHC era involves a large set of
of increasingly complicated and diverse observations from which
PDFs, TMDs, GPDs, etc…are extracted and compared to patterns
predicted theoretically.
⇒ Experimental observations can be linked to the momentum, spin, and
spatial configurations of the hadrons’ constituents.
⇒ Conventional approaches tend to explain such patterns in terms of
the microscopic properties of the theory (based on two-body interactions).
⇒We attack the problem from a different perspective:
Study the behavior of multiparticle systems as they evolve from a
large and varied number of initial conditions.
⇒ This goal is at reach within modern High Performance Computing
