Without the assumption of symmetric connection, the presence of brane fermions induces torsion. The result is a universal axial contact interaction that dominates those induced by KK gravitons. This enhancement arises from a large spin density on the brane. Using a global fit to Z–pole observables, we find the 3σ bound on the scale of quantum gravity to be 28 TeV for n = 2. If Dirac or light sterile neutrinos are present, the data from SN1987A increase the bound to √n MS ≥ 210 TeV.3765 - 3768 (4) page(s)application/pdfenIn CopyrightPhysics, MultidisciplinaryPhysicsLARGE COMPACT DIMENSIONSSCALE QUANTUM-GRAVITYCONTACT INTERACTIONSSPACE DIMENSIONSSTANDARD MODELSN 1987ACONSTRAINTSTEVMILLIMETERCOUPLINGSArticle - Refereedhttps://doi.org/10.1103/PhysRevLett.85.37658518
