Description
Any experimental analysis at the LHC requires the assessment of uncertainties in the theoretical modelling coming from neglected higher orders in perturbation theory. These are usually estimated by allowing some unphysical scale, such as the factorisation or renormalisation scale, to vary around a chosen central value.
In this project, the students will generate theoretical predictions for top-quark-pair production distributions at LHC by using the public tool MATRIX.
Several observables will be computed by using different values for the central scales and evaluating, in each case, the scale variation bands. The project aims to provide a deeper understanding of the meaning of scale variation bands as theoretical uncertainties and of the reasoning behind the choice of their central value.
