Supersymmetric particle production at hadron colliders
The theoretical status of MSSM particle production at the hadron colliders Tevatron and LHC is reviewed, including next-to-leading order supersymmetric QCD corrections. The higher-order corrections significantly reduce the theoretical uncertainty and lead to a rise of the lower bounds on supersymmetric particle masses, as demonstrated for the case of top-squark and gaugino pair production at th...
متن کاملQCD-resummation and non-minimal flavour-violation for supersymmetric particle production at hadron colliders
Cross sections for supersymmetric particles production at hadron colliders have been extensively studied in the past at leading order and also at next-to-leading order of perturbative QCD. The radiative corrections include large logarithms which have to be resummed to all orders in the strong coupling constant in order to get reliable perturbative results. In this work, we perform a first and e...
متن کاملHiggs and SUSY Particle Production at Hadron Colliders
The theoretical status of Higgs boson and supersymmetric particle production at hadron colliders is reviewed with particular emphasis on recent results and open problems.
متن کاملStop production at hadron colliders
Stop particles are expected to be the lightest squarks in supersymmetric theories and the search for these particles is an important experimental task. We therefore present the cross sections for the production processes pp̄/pp → t̃1t1 and t̃2t2 at Tevatron and LHC energies in next-to-leading order supersymmetric QCD. The corrections stabilize the theoretical predictions for the cross sections, an...
متن کاملBilepton Production at Hadron Colliders
We examine, as model-independently as possible, the production of bileptons at hadron colliders. When a particular model is necessary or useful, we choose the 3-3-1 model. We consider a variety of processes: qq̄ → Y Y −−, ud̄ → Y Y −, ūd → Y Y −−, qq̄ → Y ++e−e−, qq̄ → φ++φ−−, ud̄ → φ++φ−, and ūd → φ+φ−−, where Y and φ are vector and scalar bileptons, respectively. Given the present low-energy const...
