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...

The decays ¯ B → ¯ KD and ¯ B → ¯ K ¯ D taking into account final state interactions are discussed. These decays are described by four strong phases δ 0 , δ 1 , ˜ δ 0 , ˜ δ 1 (subscript 0 and 1 refer to I = 0 and I = 1 isospin final states), one weak phase γ and four real amplitudes. Isospin constraints are taken into account. It is argued that strong interaction dynamics gives δ 1 ≈ ˜ δ 1. The...

It is important to understand charmless three-body B decays to probe the standard model. These decays are sensitive to CP violation and supply information on strong interactions. To interpret in a reliable way weak decay observables it is important to take into account final state interactions between produced meson pairs. In the weak decays B → ππK [ 1, 2] one sees maxima around the ππ effecti...

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
