Show affiliationsWe identify the lowest-dimension interaction which is possible between standard model brane fields and bulk scalars in six dimensions. The lowest-dimension interaction is unique and involves a trilinear coupling between the standard model Higgs boson and the bulk scalar. Because this interaction has a dimensionless coupling, it depends only logarithmically on ultraviolet mass scales and heavy physics need not decouple from it. We compute its influence on Higgs physics at ATLAS and identify how large a coupling can be detected at the LHC. Besides providing a potentially interesting signal in Higgs-boson searches, such couplings provide a major observational constraint on 6D large-extra-dimensional models with scalars in the bulk.
