We consider the generalized gauge mediated supersymmetry breaking (GMSB)
models with the messenger elds which do not form the complete multiplets of SU(5)
GUT symmetry. Such a situation may happen in the anomalous U(1) GUT scenario
because the mass spectrum of the superheavy particle does not respect SU(5) GUT
symmetry, although the success of the gauge coupling uni cation can be explained.
In this paper, we assume that one pair of the messenger elds gives the dominant
contribution, and the LHC signature for the two possible messengers, X + X and
Q + Q, are examined. We investigate the possibility to measure the deviation from
the usual GUT relation of the gaugino masses which is one of the most important
features of these scenarios.
