چکیده
We point out that interesting signals of the non-strongly interacting sector of the supersymmetric standard model arise from the production of charginos and neutralinos via vector boson fusion (VBF) at the Large Hadron Collider (LHC). In particular, if R-parity is violated, the hadronically quiet signals of charginos and neutralinos through direct production get considerably suppressed. We show that in such cases, the VBF channel can be useful in identifying this sector through clean and background-free final states.

متن کاملInvisible charginos and neutralinos from gauge boson fusion: a way to explore anomaly mediation.
We point out that vector boson fusion at the Large Hadron Collider (LHC) can lead to useful signals for charginos and neutralinos in supersymmetric scenarios where these particles are almost invisible. The proposed signals are just two forward jets with missing transverse energy. It is shown that, in this way, one can put by far the strongest constraint on the parameter space of a theory with a...
متن کاملSearch for dark matter and supersymmetry in the vector boson fusion topology in proton- proton collisions at CMS
A search for pair production of dark matter candidates and supersymmetry (SUSY) production with two jets in vector-boson fusion (VBF) topology is presented using data collected by the Compact Muon Solenoid (CMS) detector in proton-proton collisions at the Large Hadron Collider (LHC). Final states with no leptons are expected in pair production of dark matter particles or scalar quarks in SUSY c...
متن کاملNext-to-leading Order Calculation of Associated Production of Gauginos and Gluinos
Results are presented of a next-to-leading order calculation in perturbative QCD of the production of charginos and neutralinos in association with gluinos at hadron colliders. Predictions for total and differential cross sections are shown at the energies of the Fermilab Tevatron and CERN Large Hadron Collider for a typical supergravity model of the sparticle mass spectrum and for a light glui...
متن کاملAssociated Production of Gauginos and Gluinos at Hadron Colliders in Next-to-Leading Order SUSY-QCD
We report a next-to-leading order (NLO) calculation of the production of gaugino-like charginos (χ̃) and neutralinos (χ̃0) in association with gluinos (g̃) at hadron colliders, including the strong corrections from colored particles and sparticles. We provide predictions of inclusive cross sections at the Fermilab Tevatron and CERN LHC. The NLO contributions increase the sizes of the cross section...
