The latest jet data from the Large Hadron Collider is studied in the context of the MSTW Parton Distribution Functions (PDFs). 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.
