Description
Minimal Gauge Mediation has been under severe stress since
the discovery of the Higgs Boson at 125 GeV. In the present
talk, we propose solution which do not introduce messenger-
matter mixing. We show that an extra U(1) factor in addition
to the Standard Model gauge group can significantly alter
the situation. A U(1) charged, Standard Model singlet is assumed
to be present which allows for an additional NMSSM like coupling,
\lambda H_u H_d S. The U(1) is assumed to be flavour universal.
Anomaly cancellation in the MSSM sector requires additional
coloured degrees of freedom. The S field can get a large vacuum
expectation value along with consistent electroweak symmetry
breaking. It is shown that the lightest CP even Higgs boson
can attain mass of the order of 125 GeV.
