This proceeding is based on hep‐th/0605225 and it shows that the most general anomaly related effective action contains Stückelberg, axionic and Chern‐Simons‐like couplings. Such couplings are generically non‐trivial in orientifold string vacua. A similar analysis in quantum field theories provides similar couplings. These Chern‐Simons couplings generate new signals which might be visible at LHC.
