eps'/eps in the standard model with hadronic matrix elements from the chiral quark model
M. Fabbrichesi
I discuss the estimate of the CP-violating parameter eps'/eps based on hadronic matrix elements computed in the chiral quark model. This estimate suggested, before the current expe…

About the Matrix model computation of three-graviton scattering
Marco Fabbrichesi, Gabriele Ferretti, Roberto Iengo
It is briefly explained why recent claims about the vanishing of the one-loop effective potential in Matrix theory, thus invalidating the possible agreement with supergravity, do n…

The Selection Rule. A Review
M. Fabbrichesi
I review a recent attempt to reproduce the isospin and 2 amplitudes for the decay of a kaon into two pions by estimating the relevant hadronic matrix elements in the chiral…
