摘要
Torsion appears due to fermions coupled to gravity and leads to the strongest particle physics bounds on flat extra dimensions. In this work, I consider torsion constraints in the case of a warped extra dimension with brane and bulk fermions. From current data I obtain a 3sigma bound on the TeV-brane mass scale Lambda(pi)greater than or equal to2.2 (10) TeV for the anti-de Sitter curvature k=1(0.01) in (reduced) Planck units. If Dirac or light sterile neutrinos reside on the brane, the bound increases to 17 (78) TeV.
