  Inclusive $A(e,e')X$ and semi-inclusive $A(e,e'N)X$ deep inelastic electron
scattering processes off few-nucleon systems are investigated at $x > 1$,
showing some of the relevant features of the cross section which are sensitive
to the effects arising from nucleon-nucleon correlations and possible exotic
multiquark cluster configurations at short internucleon separations.
