A novel study of QCD with final state jet correlations at the LHC.

The main objective of the project is to perform a thorough study of QCD by conducting precise and novel measurements with the CMS experiment at the LHC using the new RunII data with a centre- of-mass energy of vs = 13 TeV. We want to focus on the experimental measurements of processes that challenge the mainstream collinear factorisation approach that is complemented with phenomenological models. In particular the study of final state jet correlations yields an excellent sensitivity to the physics of interest. The outcome of these measurements is a direct input for the theory community and provides feedback to the phenomenological groups that develop Monte Carlo event generator models. The goal is to actively contribute to an innovation of the research field, by proposing and studying new observables or analysis techniques that can lead to reduced systematic uncertainties or sensitivity to new dynamical effects in QCD. In addition, conventional studies of QCD are performed with low luminosity data that will become less common at high luminosity hadron colliders like the LHC, the last part of the project therefore aims to investigate the feasibility of future QCD measurements in high pile-up conditions.
