A Phenomenological Model for π andKMeson Decays

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 VIOLATION IN K ± → π ± π + π − DECAYS BY NA48/2 a

First preliminary measurement of the direct CP-violating parameter Ag by the NA48/2 experiment at CERN SPS is presented. Using more than 1.6 billions of charged kaon decays into three charged pions, the charge asymmetry in the K

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 ...

A Phenomenological Model for QSOs

A combined model on the basis of generalized Field-Colgate and Terlevich-Melnick models are proposed for QSOs. Using LBQS data, it seems that the predictions of the model is confirmed by observations. The behavior of comoving density versus redshift is consistent with LDDE for QSQs. Considering the cosmic evolution of SFR, a unified aspect for origin and evolution of QSOs and ordinary galaxies ...
