Jet fragmentation transverse momentum from h-h correlations in pp and p-Pb collisions

The main contributions of the author to the research presented in this thesis are listed below. – Commissioning and maintenance of the level-0 trigger of the electromagnetic calorimeter at the ALICE experiment. – Jet fragmentation transverse momentum (jT) analysis for √s = 7 TeV pp data and √sNN = 5.02 TeV p–Pb data. – Implementation for the observable jT – Implementation for the background of the jT distribution – Deriving the acceptance correction for the analysis – Validating analysis assumptions using PYTHIA 8 simulation – Fitting the measured jT distributions – Deriving the final results from the fit parameters – Systematic uncertainty analysis – Interpretation of the results and comparing data to models
