Abstract
Let be a nonsingular cubic hypersurface. Faenzi (\cite{F}) and later Pons-Llopis and Tonini (\cite{PLT}) have completely characterized ACM line bundles over . As a natural continuation of their study in the non-ACM direction, in this paper, we completely classify -away ACM line bundles (introduced recently by Gawron and Genc (\cite{GG})) over , when . For , we give examples of -away ACM line bundles on and for each , we establish the existence of smooth hypersurfaces of degree in admitting -away ACM line bundles.
