Hadronic structure in τ− → π− π− π+ ντ decays

Measurement of the - - + - branching fraction and a τ → ηπ π π ντ search for a second - class current in the - ( 958 ) - decay τ → η π ντ ′

Search 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 ...

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 ...

Se p 20 07 Physics of η ′ → π + π − η and η ′ → π + π − π 0 decays

The article describes experimental status of the η ′ → π+π−η and η ′ → π+π−π0 decays. A theoretical framework used for description of the decays mechanism is also reviewed. The possibilities for the measurements with WASA-at-COSY are mentioned.
