0 Observation of the φ → π + π − π + π − Decay
Using 11.6 pb of data collected in the energy range 0.984–1.06 GeV by CMD-2 at VEPP-2M, the cross section of the reaction e+e− → π+π−π+π− has been studied. For the first time an interference pattern was observed in the energy dependence of the cross section near the φ meson. The branching ratio of the φ → π+π−π+π− decay double suppressed by the G-parity and OZI rule is measured Br(φ → ππππ) = (...
متن کاملSearch 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 ...
متن کاملSearch for CP-Violation in D→ π π π Decays
I have searched for a CP violating asymmetry in the neutral charm meson decay of D -> π 0 π 0 π 0 . I present here a brief description of CP violation and the CLEO II.V detector, the methods used to conduct this search, and the initial measured branching ratio of the studied decay, as well as the initial measured asymmetry of the final state of the decay. Background information: Symmetries and ...
