Phenomenology of antigravity in N=2,8 supergravity

S. Bellucci

$N = 2, 8$ supergravity predicts antigravity (gravivector and graviscalar) fields in the graviton supermultiplet. Data on the binary pulsar PSR 1913+16, tests of the equivalence princ…

S. Bellucci

We begin herewith the editing of physics notes taken in the course of Journal Club seminars at INFN-LNF in 1996. The activity consists of informal talks about work in progress and/…

Experimental limits on antigravity in extended supergravity

S. Bellucci, V. Faraoni

The available tests of the equivalence principle constrain the mass of the Higgs-like boson appearing in extended supergravity theories. We determine the constraints imposed by the…

$γ γ \to π^{0} π^{0}$ and $η \to π^{0} γ γ$ at low energy within the Extended Nambu Jona-Lasinio Model

S. Bellucci, C. Bruno

Within the Extended Nambu Jona-Lasinio model, we calculate the $O (p^{6})$ counterterms entering the low-energy expansion of the $γ γ \to π^{0} π^{0}$ and the $η \to π^{0} γ γ$ amplitudes in Ch…

Low-Energy Photon-Photon Collisions to Two-Loop Order

S. Bellucci, J. Gasser, M. E. Sainio

We evaluate the amplitude for $γ γ \to π^{0} π^{0}$ to two loops in chiral perturbation theory. The three new counterterms which enter at this order in the low-energy expansion a…
