In this thesis, I study cross sections for production of supersymmetric particles at next-to-leading order (NLO) in perturbation theory in quantum chromodynamics (QCD) at proton-proton colliders. Supersymmetry as a theory aims to correct shortcomings of the current Standard Model of particle physics, and while supersymmetry has not been confirmed at the Large Hadron Collider, proposed higher energy colliders may hold the key to discovering particles fundamental to the theory and confirming its validity. This analysis focused on supersymmetric particle production at future proton-proton colliders, given current mass constraints from the Large Hadron Collider in conjunction with future collider energies currently under proposal. Analysis utilized the Prospino2 software to calculate cross sections of event production for these particles at next-to-leading order accuracy as a function of center of mass energy, which was varied continuously between 7 and 100 TeV, as well as probing a wide range of supersymmetric parameter space and testing mass dependence between parameters with continuously varying masses at several fixed energies. Specific particles for which event production cross sections are calculated are gluinos, squarks (including stops), sleptons, charginos, and neutralinos.
