Study of the Drell-Yan process at high invariant mass at the LHC at √ s = 8 TeV
In 2012, CMS experiment took data at an energy so high as 8 TeV in the centreof-mass system, scale that had never been reached before with protons in laboratory. Such an energy opens new regions of the phase space: consequently, we hope to be able to look at the quarks at smaller scales than ever do...

| Sumario: | In 2012, CMS experiment took data at an energy so high as 8 TeV in the centreof-mass
system, scale that had never been reached before with protons in laboratory.
Such an energy opens new regions of the phase space: consequently, we hope to be
able to look at the quarks at smaller scales than ever done before. This master thesis
presents an analysis of the Drell-Yan process in CMS data, as well as a study of the
introduction of form factors for the quarks in the expression of the cross section to
optimize the fitting between data and simulations. |
