Tests of signal locality and Einstein-Bell locality for multiparticle systems

For multiparticle systems we formulate the notions of signal locality (i.e., absence of faster-than-light signaling) and Einstein-Bell locality (or local realism) and obtain inequalities between experimental correlation functions to test them. Quantum theory obeys signal locality but violates Einstein-Bell locality by a factor $2^{\left(\mathit{n}\mathrm{-}1\right)/2}$ for n-particle systems.
