Gravitons in multiply warped scenarios - at 750 GeV and beyond

Understand

The search for extra dimensions has so far yielded no positive results at the LHC.

• Along with the discovery of a 125 GeV Higgs boson, this implies a moderate degree of fine tuning in the parameter space of the Randall-Sundrum model.
• Within a 6-dimensional warped compactification scenario, with its own interesting phenomenological consequences, the parameters associated with the additional spatial direction can be used to eliminate the need for fine tuning.
• We examine the constraints on this model due to the 8 TeV LHC data and survey the parameter space that could be probed at the 14 TeV run of the LHC.
