Analysis on the f 0 ( 600 ) and f 0 ( 980 ) Resonances in γγ → π + π − , π 0 π 0 Processes

We estimate the di-photon coupling of f0(600), f0(980) and f2(1270) resonances in a couple channel dispersive approach. Especially we estimate the di-photon coupling of the third sheet pole located near K̄K threshold, denoted as f III 0 (980). It is argued that this third sheet pole may be originated from a couple channel Breit-Wigner description of the f0(980) resonance. The f0(600) di-photon c...

Search for direct CP violating charge asymmetries in K ± → π ± π + π − and K ± → π ± π 0 π 0 decays

A measurement of the direct CP violating charge asymmetries of the Dalitz plot linear slopes Ag = (g + − g)/(g + g) in K → πππ and K → πππ decays by the NA48/2 experiment at CERN SPS is presented. A new technique of asymmetry measurement involving simultaneous K and K beams and a large data sample collected allowed a result of an unprecedented precision. The charge asymmetries were measured to ...

B 0 / B 0 Decays to π + π − π 0 and K ± π ∓ π 0 in Regions Dominated by the ρ ± Resonance

We present preliminary measurements of direct and indirect CP -violating asymmetries in the decays of neutral B mesons to π+π−π0 and K±π∓π0 final states dominated by the ρ± resonance, using a time-dependent maximum likelihood analysis. The data sample comprises 88 × 106 Υ (4S) → BB decays (80.8 fb) collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. For the CP v...
