GAGRA (Gauge Theories and Gravity)
GAGRA is an INFN national specific initiative whose aim is, among other ones, to employ new methods based on recent developments (M.Bochicchio [1,2,3]) for the understanding of confining asymptotically free gauge theories - specifically of the ’t Hooft large-N limit of QCD - and for the consistent quantization of gravity (D.Anselmi [4,5,6]) that do not rely either on the simplifications furnished by the supersymmetry or on the superstring unification of all the interactions respectively.
A key role in the development of the aforementioned methods is played by the high-energy features of both large-N QCD (M.Bochicchio [1,3]) or, more generally, asymptotically free gauge theories, and of gravity (D.Anselmi [4,5]), mostly in relation to the non-perturbative (M.Bochicchio [1,3], M.Papinutto [7], D.Anselmi [4,6], F.Scardino) and perturbative (M.Becchetti [8], A.Quadri [9]) renormalization properties of the S-matrix amplitudes and correlators.
Moreover, complementary - but crucial - aims are the exploration of the non-perturbative low-energy features of QCD by lattice gauge theories (M.Papinutto, F.Russo) and QCD phenomenology (A.Polosa [10], A.Pilloni [10]) and, on the gravity side, the experimental search for dark matter (A.Polosa [11]).
