Summary
In order to reproduce the measured mass of the Higgs boson in the minimal supersymmetric standard model, one usually has to rely on heavy stops. By introducing a new gauge sector, the Higgs mass gets a tree-level contribution via a non-decoupling D-term, and the stops are allowed to be lighter. We study the values of the stops masses in a setup where the gauge group is extended by a single U(1)x interaction. We derive the experimental limits on the mass of the Z' gauge boson in this setup using LHC-13 data. We then explore the parameter space relevant for the stop masses assuming the discovery of a Z' resonance with LHC-14.
