Scalar Mesons In Radiative Phi-meson Decays Into Neutral K-meson StatesSisman Korkmaz, Canan 01 September 2006 (has links) (PDF)
Radiative Decays of the phi-meson to the scalar mesons f0(980) and a0(980) are investigated within the framework of charged kaon loop model for both point-like scalar mesons and for scalar mesons with extended structure. Then, the radiative phi-meson decay into neutral K-meson is studied via a two step mechanism in which the scalar mesons couple the final state to the phi-meson through the charged kaon loop. The branching ratio of this decay is calculated and it is shown that this reaction will not provide a significant background to the measurements of phi-meson into neutral K-meson states decay for testing CP violation.

Scalar Mesons In Radiative Phi-meson Decays Into Charged K-meson StatesOzturk, Fahri 01 June 2008 (has links) (PDF)
The role of $f_{0}(980)$ and
$a_{0}(980)$ scalar meson intermediate states in the mechanism of
radiative $phi (1020)$ meson decay into two charged $K (494)$
mesons and a photon $phirightarrow K^{+} + K^{-} + gamma$ is
investigated. For the contribution of scalar meson intermediate
state two models are considered. In the kaon-loop model, the scalar
meson intermediate state couples the final state to the initial
$phi$ meson through a charged kaon-loop. The second model, called
no-structure model, consist of point-like coupling of intermediate
scalar meson state to the initial state. It is found that in the
kaon-loop model, scalar meson intermediate state results in a
considerable modification of the pure Bremsstrahlung photon
spectrum.
