Description
We examine the possibility of detecting signals of split supersymmetry in the loop-
induced decay h --> gamma gamma of the Higgs boson at the Large Hadron Collider,
where charginos, as surviving light fermions of the supersymmetric spectrum, can
contribute in the loop. We perform a detailed study of uncertainties in various
parameters involved in the analysis, and thus the net uncertainty in the standard
model prediction of the rate. After a thorough scan of the parameter space, taking
all constraints into account, we conclude that it is very unlikely that signals for
Split Supersymmetry can be detected in Higgs signals at the LHC and one would require
a linear collider to be able to make a distinction.
