Stop 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...

Bilepton 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...

Production of exotic hadrons at hadron colliders

The observation of many unexpected states decaying into heavy quarkonia has challenged the usual QQ̄ interpretation. One of the most studied exotic states, the X(3872), happens to be copiously produced in high-energy hadron collisions. We discuss how this large prompt production cross-section disfavors a loosely-bound molecule interpretation for this particle. This is supported by Monte Carlo si...

Squark and Gluino Production at Hadron Colliders

We have determined the theoretical predictions for the cross-sections of squark and gluino production at pp̄ and pp colliders (Tevatron and LHC) in next-to-leading order of supersymmetric QCD. By reducing the dependence on the renormalization/factorization scale considerably, the theoretically predicted values for the cross-sections are much more stable if these higher-order corrections are impl...
