Abstract.We consider the collider phenomenology of split-supersymmetry models. Despite the challenging nature of the signals in these models the long-lived gluino can be discovered with masses above 2 TeV at the LHC. At a future linear collider we will be able to observe the renormalization group effects from split supersymmetry, using measurements of the neutralino and chargino masses and cross sections. 
Signatures of Supersymmetry at the LHC
We briefly review the aspects of supersymmetry (SUSY) and SUSY breaking necessary for appreciating the prospect of discovering supersymmetric particles at the Large Hadron Collider (LHC), avoiding
Higgs boson mass in split supersymmetry at two-loops
The mass of the Higgs boson in the split-supersymmetric standard model is calculated, including all one-loop threshold effects and the renormalization group evolution of the Higgs quartic coupling
On measuring Split-SUSY neutralino and chargino masses at the LHC
In Split-Supersymmetry models, where the only non-Standard Model states produceable at LHC-energies consist of a gluino plus neutralinos and charginos, it is conventionally accepted that only mass
Distinguishing split supersymmetry in Higgs signals at the CERN Large Hadron Collider
We examine the possibility of detecting signals of split supersymmetry in the loop-induced decay h{yields}{gamma}{gamma} of the Higgs boson at the Large Hadron Collider, where charginos, as surviving
Measuring supersymmetry with heavy scalars
Supersymmetry with heavy scalars is a model where, at the LHC we have to rely on rate measurements to determine the parameters of the underlying new physics. For this example we show how to combine
Splitting split supersymmetry
In split supersymmetry, the supersymmetric scalar particles are all very heavy, at least at the order of 10{sup 9} GeV, but the gauginos, Higgsinos, and one of the neutral Higgs bosons remain below a
Supersymmetry phenomenology beyond the MSSM after 5/fb of LHC data
We briefly review the status of motivated beyond-the-MSSM phenomenology in the light of the LHC searches to date. In particular, we discuss the conceptual consequences of the exclusion bounds, of the
SPLIT SUPERSYMMETRY AND THE ROLE OF A LIGHT FERMION IN A SUPERGRAVITY-BASED SCENARIO
We investigate split supersymmetry (SUSY) within a supergravity framework, where local SUSY is broken by the F-term of a hidden sector chiral superfield X. With reasonably general assumptions, we

Implications of SUSY model building
TLDR
The case is presented for the minimal supersymmetric standard model, which is in agreement with all present experimental results, and yet depends on only a few unknown parameters and therefore maintains considerable predictive power.
Can we distinguish between hSM and h0 in split supersymmetry
We investigate the possibility of distinguishing between the standard model higgs boson and the lightest Higgs boson in split supersymmetry. We point out that the best way to distinguish between
