The effect of recent ATLAS inclusive- and dijet results on the current standard PDF sets is investigated, compared and contrasted to similar results from the Tevatron. A parton reweighting technique is used to gain information on the optimum PDFs for each new data set. New PDF sets are produced and studied using the new LHC data. These jet results provide a new central value of the PDF and reduce the uncertainty on the distributions. Additionally, a new method of parametrising the quark PDFs using Chebyshev Polynomials is tested in relation to the ATLAS W/Z rapidity data, which is described poorly using the standard PDFs. The effect of parton showering on jet physics is studied using various shower Monte Carlo generators within the context of jets produced in deep inelastic scattering, and the possibility of using charged current jet production in PDF fits is tested. date: 2014-02-28 vfaculties: VMPS oa_status: green full_text_type: other thesis_class: doctoral_open language: eng thesis_view: UCL_Thesis dart: DART-Europe primo: open primo_central: open_green verified: verified_manual elements_source: Manually entered elements_id: 931272 language_elements: EN lyricists_name: Watt, Benjamin lyricists_id: BJAWA51 full_text_status: public pagerange: 1 - 170 pages: 170 institution: UCL (University College London) department: Physics and Astronomy thesis_type: Doctoral citation: Watt, BJA; (2014) Investigations into the effect of Hadron Collider data on MSTW Parton Distribution Functions.
