Determination of Non-Universal Supergravity Models at the Large Hadron Collider

Understand

We examine a well motivated non-universal supergravity model where the Higgs boson masses are not unified with the other scalars at the grand unified scale at the LHC.

• The dark matter content can easily be satisfied in this model by having a larger Higgsino component in the lightest neutralino.
• Typical final states in such a scenario at the LHC involve W bosons.
• We develop a bi-event subtraction technique to remove a huge combinatorial background to identify W -> jj decays.
