We study phenomenologically the scenario in which the scalar top quark is lighter than any other standard supersymmetric partner and also lighter than the top quark, so that it decays to the gravitino via {tilde t} {yields} W{sup +}b{tilde G}. In this case, scalar top quark events would seem to be very difficult to separate from top quark pair production. However, we show that, even at a hadron collider, it is possible to distinguish these two reactions. We show also that the longitudinal…

Very light scalar top quarks at the LHC

A very light scalar top (stop) superpartner is motivated by naturalness and electroweak baryogenesis. When the mass of the stop is less than the sum of the masses of the top quark and the lightest

Natural gauge mediation with a Bino next-to-lightest supersymmetric particle at the LHC.

The ATLAS diphoton search with 4.8 b(-1) of data is used to place limits in both the top-squark-gluino and neutralino-chargino mass planes, providing the first nontrivial constraints in natural gauge mediation models with a neutralino next-to-lightest supersymmetric particle decaying to photons.

Natural supersymmetry at the LHC

If the minimal supersymmetric standard model is the solution to the hierarchy problem, the scalar top quark (stop) and the Higgsino should weigh around the electroweak scale such as 200GeV. A low

Neutralino reconstruction in supersymmetry with long-lived staus

We consider a supergravity scenario, with universal scalar and gaugino masses at high scale, with a right-chiral neutrino superfield included in the spectrum. Such a scenario can have the lightest

Dark matter, light top squarks, and electroweak baryogenesis

We examine the neutralino relic density in the presence of a light top squark, such as the one required for the realization of the electroweak baryogenesis mechanism, within the minimal

Right-chiral sneutrinos and long-lived staus: Event characteristics at the CERN Large Hadron Collider

We investigate the signals of a supersymmetric scenario where the lighter tau-sneutrino is the lightest supersymmetric particle, while the lighter stau-state is the next lightest. We confirm that

Reconstruction of the left-chiral tau-sneutrino in supersymmetry with a right-sneutrino as the lightest supersymmetric particle

We have considered a supersymmetric scenario in which the minimal supersymmetric standard model is augmented with a right-chiral neutrino superfield for each generation. Such a scenario can have a

Top squark searches at the Tevatron in models of low-energy supersymmetry breaking

We study the production and decays of top squarks at the Fermilab Tevatron collider in models of low-energy supersymmetry breaking. We consider the case where the lightest standard model (SM)

Stop decay into right-handed sneutrino LSP at hadron colliders

Right-handed neutrinos offer us the possibility of accommodating neutrino masses. In a supersymmetric model, this implies the existence of right-handed sneutrinos. Right-handed sneutrinos are

Natural gauge mediation with a bino NLSP at the LHC

Natural models of supersymmetry with a gravitino LSP provide distinctive signatures at the LHC. For a neutralino NLSP, sparticles can decay to two high energy photons plus missing energy. We use the
