B decays into ππK and KKK, where the ππ and KK pairs interact in isospin zero S-wave, are studied in the ππ effective mass range from threshold to 1.2 GeV. The interplay of strong and weak decay amplitudes is analyzed using an unitary ππ and KK coupled channel model. Final state interactions are described in terms of four scalar form factors constrained by unitarity and chiral perturbation theo...

We show using Mean Field Theory that the phase diagram of QCD at finite density (T = 0) is such that chiral symmetry remains spontaeously broken at all density! Talk given at the Recontres Vietnam, Hanoi, August 2004

We investigate the relativistic Fermi motion effect in the case of J/ψ production in various hadron colliders. A light-cone wave function is adopted to represent the J/ψ final state. The change in the confinement parameter which sets a scale for the size of the final state, allows one to see the effect in an explicit manner. While the effect has considerable influence on the fragmentation proba...
