The significance of final-state interactions in B_d-->\pi\pi decays is phenomenologically demonstrated by taking elastic \pi\pi--\pi\pi and inelastic \pi\pi--D\bar{D} rescattering effects into consideration. We find that the present…
We have studied the Dalitz plot of the e+ e- --> pi0 pi0 gamma events collected at SQRT(s) ~ M(phi) with the KLOE detector. In the dipion invariant mass (Mpp) region below 700 MeV, the process under study is dominated by the non-resonant…
