The s-sbar and K-Kbar nature of f_0(980) in D_s decays
A. Deandrea, R. Gatto, G. Nardulli +2
We examine the D_s -> f_0(980) pi amplitude through a constituent quark-meson model, incorporating heavy quark and chiral symmetries, finding a good agreement with the recent E791…
Dispersion Laws for In-medium Fermions and Gluons in the CFL Phase of QCD
R. Casalbuoni, R. Gatto, G. Nardulli
We evaluate several quantities appearing in the effective lagrangian for the color-flavor locked phase of high density QCD using a formalism which exploits the approximate decoupli…
Chiral Meson Masses at Finite Temperature and Density
A. Barducci, R. Casalbuoni, R. Gatto +1
The ratio of the sigma mass to the pion mass at finite temperatures and densities provides for a quantitative signal of chiral symmetry breaking. We calculate this ratio by using a…
B and B_s decays into three pseudoscalar mesons and the determination of the angle gamma of the unitarity triangle
A. Deandrea, R. Gatto, M. Ladisa +2
We reconsider two classical proposals for the determination of the angle gamma of the unitarity triangle: B^\pm => chi_{c0} π^\pm => π^+π^-π^\pm and B_s => rho^0 K_S => π^+ π^- K_S…
Z' indication from new APV data in Cesium and searches at linear colliders
R. Casalbuoni, S. De Curtis, D. Dominici +2
New data on parity violation in atomic cesium can be explained by a new neutral vector boson almost unmixed with Z, with a mass in the TeV range and sizeable couplings to the fermi…
